Been a long ass time since I uploaded on this channel, I know. Even though I've been uploading on the second channel, I missed you guys over here. 😭 Roadmap: neetcode.io/roadmap Quiz feature: neetcode.io/practice Second channel: youtube.com/@neetcodeio
I will leave one little story here, as it relates to this video. If you are someone that feels like you are not smart enough to succeed, then this story is for you. I was one of the worst students back in my middle school. I remember being the only one not able to understand stuff in math class that basically everyone understood. The teacher even pulled me aside to talk to me. Failing lots of tests, from multiple subjects... even though I studied a decent amount of time... Eventually, I realized I needed to increase my intelligence. This is different from getting good grades. This is about increasing your comprehension, creativity and brainpower. I thought that math problems, not those from school, were the path. So I started at them. I started easy, getting the easiest math olympiad problems I could find. Some are really easy, but even those took me lots of time reading the solutions to understand. But eventually, these started to actually become understandable to me... so I started ramping up the difficulty... I spent hours and hours everyday solving these problems, and eventually reached IMO level (International Mathematical Olympiad - though I did not make it to the actual team, I was selected as one of the potential participants, but basically everyone on the team selection tests were at least bronze level). I also became one of the top students from my country, and also a National Math and Informatics Olympic medalist. I studied for free at the top school, by getting the highest markings on the scholarship competition. It took a few years of daily study, but patience is a huge monster skill to have. Your brain just takes time to build itself. You wouldn't think of rushing a broken arm, right? Afterwards I got scouted by a top investment bank... at their best trading desk. Got the top score on their logic test by a mile. But this is getting out of topic. What I want to teach with this story of mine is that even if you are not too smart now, you can become a top tier intellectual being by sheer effort, unless maybe if you have a special condition. But in general, if you do this, solve lots of math problems, ramping up difficulty until you reach international level, you WILL become a supreme genius. Every one of the math champions that I met worked very hard to reach that level. All of them entered top schools, top jobs, etc. It really is a matter of putting in the hours... I did maybe 2 or 3 hours of math solving everyday, some days on vacation from school I did 4, 6 or 10 hours... It is a lot of work, but I guess most of the great rewards come from hard, grueling work. And mind you, I was in middle/high school. Some practical tips: get easy problems first, and try to learn one per day until you get the habit. Note that I used "learn" instead of "solve". Focus on raising your understanding, not on immediately being a top solver. Try all your obvious ideas first, and if that does not work, than start a timer for 15 minutes. Think for 15 minutes, searching for new ideas. Then read part of the solution, and try to finish the rest. Keep doing it until you get the entire solution. Also, try to understand how you could have reached that solution. How did the guy who solved it think about such an esoteric idea? You need to ponder these kinds of things, to increase your intuition. Sketch a lot. You need pen and paper. Read how the top math champions came to be and read their tips. Hope this helps someone, and also that I did not come off as arrogant. It is hard to talk about these experiences without causing the impression of "showing off" or something like that. But I also believe it may help someone. I for sure would have liked to read these words back in the day. Would have sped up my progress. If you feel you do not have a future, please believe that you can have a great life. I know it seems hopeless sometimes, but our comprehension gets limited when attacked by extreme stress and sadness. Work hard, have patience, it takes a few years, but if you put in the effort on the right things, you will most probably achieve "success". Though by then your definition of success will probably be different. Edited for typos.
Hey friend, what resources did you use to study? Did you watch youtube videos, read a book, use some site, solved past papers, went to workshops, etc.? I've been struggling to find resources as a person who does self-study, I look up past math contests to solve but couldn't find where anyone learns the topics. I really admire your story and your help here will be greatly appreciated.

I'm at 100 problems. What you're saying right now is really resonating with me. I used to feel the same way, hopeless and wanting to quit when I started and couldn't solve even easy questions, now easy questions are pretty okay for me. I hope the road gets easier just like you mentioned here. Thanks for this video. This is exactly what I needed.

But this video changed my misconception and I am really glad that I didn't waste my time and used my time efficiently..... TBH I think I am the happiest person on earth after knowing this!!
Thank you so much for this video 😭. Started doing the leetcode 150 about two weeks ago and im glad i got some tips about how to get throught it. Definitely going to be referring to these links and channel in thr future 🤙
I think leetcode is a good use of time in general too because it re-programs how you think and hones out your mental edge. I've only been seriously preparing for a short time and I feel that I can approach things more analytically than before. That is always an invaluable skill in development because when the difference between a test passing or failing in your MR is a mis-handled edge case the leetcode part of your mind should help take over and figure out what's wrong. Love your site and videos, really well explained in a global economy where millions of people can code but few can explain it well, and even fewer can do so in fluent English with relatable abstractions to understand the approach.
This is entirely true, I see people bitching about how "there's no real value whatsoever", but still wrap there code in giant IF statements instead of returning edge cases at the start of a method.
Bro, I have started this Leetcode journey with your course. I hope one day I will be good enough to get a decent job. Thanks, you are really an inspiration.
You said 50 leetcode problems helped you get an internship at a bank, but how? Once you have developed some mastery of these problems, how do you market such traits to potential employers?
Thanks a lot Navdeep for the website. I still can't believe the practice section is free of cost, the fast reviews are literally what ed-tech websites charge money for, I've faced almost similar quizzes in interviews and thanks to you I'm motivated to finish DSA/Leetcode otherwise I might've given up on it. Thanks for being so generous for the community may god bless you with more gifts in life. You deserve everything you've got and are still getting man.
This man is doing god's work. After having done this grind sucessfully before, I am revisiting the same 75-90 question grind now and I was struggling more than I have before. But the video states everything so honestly. Its baking in these concepts and patterns again and again. I really needed this today. Thanks man!
I found your neetcode site about 8 months ago, and it has been the most inspirational and direction-giving thing I have come across in leet code prep. Thanks a ton!
There is a wholesome energy when you surround yourself of people that want better that i cannot explain but feel right away reading these comments. Its like a breath of fresh air We all gona make it boys, keep studying and upgrading mental skils
My thoughts as someone who's in a similar AC range and found this channel helpful when starting out: First off: Wild to think that my AC count is higher than yours at this point; the channel was an immense help when I was starting out mid-last-year, and I'll admit that my count is only as high as it was due to feverish prep before going into finals with 2Sig and JS. For what it's worth, this is coming from someone who did not target FAANG due to bad timing with interviewing (late 2022) and ended up landing in trading: Personally, I think that the point where you can consistently do 99% of problems is a bit higher than 250; I'd say that was around the 300-350 mark for me. There are some concepts that I feel are hard to get down pat until you've done then several times. Additionally, in my experience, some concepts seem like they have a habit of just not coming up as frequently (prefix sum) as others (dfs/bfs), so your chances to identify and practices them are a lot lower. They're not even necessarily hard, but if you're not used to them, they can be a pain in the rear. In terms of preparedness for tech interviews, I think it depends greatly on the company. If I were to go back and do them again now, I'd feel 95% prepared, with that 5% being due to a certain company snidely asking information theory questions (I won't say who but if you know you know). However, if I were to interview for like IBM, JPMC, BOA, etc. (and likely FAANG's not known for asking DP), I can honestly say I'd feel very confident if I had to do it tomorrow with no dedicated prep time. The interview difficulties aren't consistent, and if you interview with enough companies, you'll find that out pretty easily. It's the gap between doing a pretty straightforward sorting problem versus being asked to use bit manipulation in your OA; it's not that you're less prepared overall, but rather that you're less prepared for a specific type of interview. As far as whether solving LC is worth it past that 250-300 mark, I think it depends on your targets. If you're looking for FAANG, 250-300 is acceptable. Non-FAANG F500's you can probably get away with like 200. If you're trying to do trading firms, you need to get to that 10-15 minutes for an LC medium point, which I'd say is around the 450 mark; it's not so much that you need the algorithm knowledge, since that isn't changing much, but you need to be able to look at a problem and in 20-30 seconds know "Oh this is a UF problem" , "This is two heaps", "This is graph traversal with XYZ optimization".
Thank you so much, this video is amazing and I needed this so much. I do what you described at 3:19 with every single Medium/Hard problem. I needed this so much, thank you
I always feel like doing leetcode questions on the spot is defently a skill that requires you to maintain doing it. You can learn how to solve lots of em and recognize sort of what structures and algos should be helpful but nailing a problem quickly on an interview in like 20 mins of less requires you to keep praticing it regulary. Which feels like a giant time thief for creativity that could be spent on doing more meaningful things as at the end of the day, its mostly about being able to memorize a lot of things.
Thank you so much for your work! You made my interview preparation process so organized and even hard problems easy to come up with. And btw the newly added quiz idea is brilliant!
i appreciate you doing this video. currently im too burnt out on programming to learn more stuff, but it's helpful to know there's some seemingly easy thing i can do to make more money should i decide to go back.
@@rutabega306 lol you can't be serious saying something like that. In fact, the most lucrative jobs in techs are not even at FAANG, dunno if you're aware of that
Dman Bruh! You are a legend . I was always skeptical about my dsa learning since i didnt knew how to prepare though i had the knowledge. You showed me the way .
Was looking for information to work at Google, randomly found this channel, wow. I knew I need to work on algorithms but didn’t have a good path, like roadmap, and it looked like a too complex and long way, I was struggling to learn steadily. Your roadmap made it look so much more achievable. Have 2.5 more years in college, I’ll work and make it, hope I can tell you good result.
you know, 2-D dp arrays are actually just an abstraction for 1-D arrays since i*m + j is unique for all -1 < i < m, -1 < j < n that can be indexed in the array. Same with hashmaps.
Great video. I've been studying for the past few months. And I identify in most of the things you say and you put into words others I only had in my mind. In my experience and from what you said I highlight: - Order matters. - 1 or 2 daily is better than tons a day. - Repetition, feel free to do easy or mid or hard ones again even if you solve them in the last few months. - Look and understand other's answers.
you are doing gods word. in the video you joked about being a loser. you are far from one. you put so much effort into rising your competence then put more effort into helping others raise theirs. thank you. I discovered your channel by chance, and what a chance. Currently in the middle of semester exams. I will start this journey in my holidays.
For several years of programming, I had practically no such problems. Most of the problems are struggling with libraries, frameworks, dependencies and architecture or something like the programming language is not suitable for one part of application. At least in the area of programming that I deal with... Apart from the need for intellectual development, of course, I see no point in practicing solving such problems.
This got me hyped! That roadmap at 2:50 instantly reminded me of a skill tree from RPG games that I want to max out. I started coding 1,5 months ago with CS50X, and using gaming analogies when learning to code changes everything for me! Instant dopamine trigger😮💨 Never tried Leetcode before but it reminds me of XP farming😂
@@jimhalpert9803 Yeah exactly! Game developers know what they’re doing when designing a game to optimize dopamine rewards. So why not structure your mental picture of your learning process using the same mold as videogames? Makes it much more rewarding compared to the standard process of learning that schools give, which makes everything seem like a chore!
Thank you so much for your hardwork and dedication!!!! I have purchased your Pro Lifetime subscription already, but for the value you offer with all your videos and your website, I really want to just keep throwing money at you because how amazing your work is!!!! Your work is better than 99% of my lecturers at uni 😭 Thank you so much
@@lastyhopper2792 No you don’t have the right, because I am not a bot and I have been using this RUclips account for more than 9+ years. You look more like a bot who fails to understand why a valuable RUclipsr would receive appreciation like this, and instead, you see all grateful messages as ads. Pathetic.
solving questions and learning algorithms are as healing as meditation. no need for a faang or big tech, it saves my life in such this harsh unemployment period.
You're godsent for software engineer preparation, after watching few of your neetcode explanations it helped me understand many stuff which I might've not learnt elsewhere and you also helped me find the confidence to solve any problem, kudos to you man!
The fast review section is a game changer. If and when it's finished for all the 433 questions you have (prefereably in order , finishing blind 65 then 150 then the rest), it will be so much help to get a quick revision during the last few days of an interview.
This is the best video I've seen regarding coding preparation. I also started doing "random LeetCode" (well, the most freq asked questions at Google interviews according to LeetCode). After a year and a half I learnt about Blind 75 and Grind 75. Then now after 2 years I found this video with your roadmap graph with the order you should learn topics on. I wished I had seen this earlier as I'm sure patterns would've stack faster in my head! Thank you for doing these videos and the leetcode solutions, your contributions to the community are invaluable!
I remember spending so many horus doing LeetCode only to find out that the interviews on the companies I wanted (triple A game studios like ubisoft) literally have nothing to do with regular tech companies. I'm considering going back into it so that I maybe shift out of game dev and go back into regular programming
@@xx-wp3mq I applied to multiple and currently working for one of them and all the interviews I had were basically small tests to do on my free time. All along the likes of: build this mechanic in UE and keep the code as clean and optimized as possible. Then on the following interview they did a lot of questions about the code I did and why did I do it that way and etc. The interviews all felt a way more project-based than the ones I had for non game dev companies
One of the best channels I have always look forward to whenever I get stuck in any LeetCode daily challenge problem or any famous LeetCode interview problem. Love the content!! Hopefully someday I can land my dream job as well!! Love from India❤❤
You conclude how leetcode helps you reasoning about unit testing without argumentation, how do you figure leetcode helps people unit testing? Aside of this question I believe things like leetcode are a good addition for practise, but is it really overemphasised by big, mostly American, companies for the mere fact that it's much easier to test on applicants than more abstract concepts.
I've majored in CS two years ago and I always compared myself to my fellow classmates as they seemed to grasp programming problems way way easier than me. Even some of them went to Seattle (we're from Mexico) to work for Microsoft. As a result, I always had this imposter syndrome, and while I have landed some ok jobs at Oracle and IBM, I always felt very mediocre. I'm 25 now and my dream has always been to enter Google or Apple. I thank you so much for motivating me and thousands of people that feel the same way as me.
Absolutely, especially if you can't solve many of the problems from the NC 150 list from scratch. It's better to be really good at a small set of problems, then be bad at a large set of problems.
@@NeetCode "It's better to be really good at a small set of problems, then be bad at a large set of problems." Life wisdom right there on how to hone your skills.
@@NeetCode Should I solve all problems in one categori in neetcode them move to other categories? (Should I solve all questions of DP in bline75 before start greedy) Or just do All Easyies all categories then mediums then hard. Also, is neetcode 150 better than neetcode 75?
@@카이트-c8y In one of his videos he mentioned that it is better to solve easy questions of each category first, and then move on to medium, and then hard. That way you will learn the basics of all major categories, since you don't know from which category you will be asked.
I don't if it's I working in the energy sector or like in Germany but in all my job interviews I never had to solve any coding problems. Of course they asked questions about how I my approaching style or how I would solve something in general. But like I said, I never had to solve a generic "puzzle" 🤔 But I see the values of solving those and do it from time to time on Code Wars
The part usually not said in these videos is that if you're really good at these puzzles, you could land a $200k+ software job on the American west coast, which is an absurd amount of money in contrast to traditional "get a few years of apprenticeship and move up the career ladder" advice. Of course, that was also before the mass layoffs of 2023 and near zero interest rates, so we are in unknown territory.
First of all, let me express my gratitude for the valuable content that you have provided. I have a question that may seem trivial, but it is still significant to me. My coding journey started in 2018 when I began teaching myself without having a CS degree. I started with Python, and then progressed to web development, where I learned Django. Currently, I work as a freelance developer. Although I have considered learning DS/ALGO and applying to big tech companies, my self-doubt and uncertainty have held me back from applying. Recently, I have started practicing Leetcode problems, and while I can solve easy ones, some medium ones take a long time to solve, and hard ones seem impossible. My question is: Can an individual over 30 years old, without a degree, join FAANG or MAANG companies? I would greatly appreciate your insights on this matter.
I think the 45-60min limit per problem is important, it's happened to me on freecodecamp while doing the JS courses and it's something that is hard for me to apply because I really want to solve problems before looking into the solution. But some problems as you advance, they become more vaguely explained, with less and less detail and more complex, which can be difficult sometimes to come up with a solution, by the time you read the solution you realize that you'd probably would have never come up with anything remotely close to that so yeah, putting a time limit, looking at the solution and trying to understand it is hopefully good advice.
I am glad that I bought your lifetime subscription, whole material is already top-notch , and now this upcoming feature to review questions in Quiz form going to be amazing. I will be really grateful to you if you do this Quiz review feature for all 331 Questions, I know its a lot of work but you can release it in phases. Thank you so much for all your efforts.
i was almost give up on this, but you changed my mind, NG is hard in this year, and i only have B grade, no intern, its graduate-unemployed. thanks you and your work i might going to try again, if i did you you are NO1 i need to thanks
Strangest people are those that solve all those LeetCode problems to get into Google, thinking it will be like a "dream job" of sorts. News flash - it isn't. I got hired as L6, Staff Engineer and left after few moths to other company - Google is WAY past it's prime - it's not the company that people wanted to get into 10 years ago. It's full of tragic code, extremally slow pipelines and strange kind of "talent" - people that somehow confuse what engineering work is really about. My recommendation - stop watching "leet code" videos or solve those abstract problems - start solving real problems, in the real world - because this is what EVERY business is built around.
I don't know if it's a US thing that they are so obsessed on Leetcode problems. Where I live you basically tell them in an interview that you know their stack bla bla and then you start working with a probationary period. All they want is experience with the stack. When you tell them you solved 200 leetcode problems they will either laugh at you or ask "What is Leetcode?".
One thing I'd add about language choice is that picking a language without built-in data structures in the standard library makes it impossible to solve certain questions optimally without literally needing to implement the data structures yourself. For this reason, I moved from TypeScript to Python for this kind of question...!
Love the road map! Don't think it's entirely crucial to study backtracking prior to dynamic programming, but a recursive thinking process can certainly help with solving dp problems.
Honestly what is missed with your leetcode problems is the thought process you went thru when you first solved the problem and the actual time it look to solve it. So many of these videos make people feel like solving these are easy when they are not.

Thank you so much for this video 😭. Started doing the leetcode 150 about two weeks ago and im glad i got some tips about how to get throught it. Definitely going to be referring to these links and channel in thr future 🤙
I think leetcode is a good use of time in general too because it re-programs how you think and hones out your mental edge. I've only been seriously preparing for a short time and I feel that I can approach things more analytically than before.
That is always an invaluable skill in development because when the difference between a test passing or failing in your MR is a mis-handled edge case the leetcode part of your mind should help take over and figure out what's wrong.
Love your site and videos, really well explained in a global economy where millions of people can code but few can explain it well, and even fewer can do so in fluent English with relatable abstractions to understand the approach.
This is entirely true, I see people bitching about how "there's no real value whatsoever", but still wrap there code in giant IF statements instead of returning edge cases at the start of a method.
i thought you were going to show your brain MRI scan

Interview
Leetcode is only useful for coding challenges in interviews
Thanks a lot Navdeep for the website. I still can't believe the practice section is free of cost, the fast reviews are literally what ed-tech websites charge money for, I've faced almost similar quizzes in interviews and thanks to you I'm motivated to finish DSA/Leetcode otherwise I might've given up on it. Thanks for being so generous for the community may god bless you with more gifts in life. You deserve everything you've got and are still getting man.
This man is doing god's work. After having done this grind sucessfully before, I am revisiting the same 75-90 question grind now and I was struggling more than I have before. But the video states everything so honestly. Its baking in these concepts and patterns again and again. I really needed this today. Thanks man!
I found your neetcode site about 8 months ago, and it has been the most inspirational and direction-giving thing I have come across in leet code prep. Thanks a ton!
There is a wholesome energy when you surround yourself of people that want better that i cannot explain but feel right away reading these comments. Its like a breath of fresh air
We all gona make it boys, keep studying and upgrading mental skils
My thoughts as someone who's in a similar AC range and found this channel helpful when starting out:
First off: Wild to think that my AC count is higher than yours at this point; the channel was an immense help when I was starting out mid-last-year, and I'll admit that my count is only as high as it was due to feverish prep before going into finals with 2Sig and JS.
For what it's worth, this is coming from someone who did not target FAANG due to bad timing with interviewing (late 2022) and ended up landing in trading:
Personally, I think that the point where you can consistently do 99% of problems is a bit higher than 250; I'd say that was around the 300-350 mark for me. There are some concepts that I feel are hard to get down pat until you've done then several times. Additionally, in my experience, some concepts seem like they have a habit of just not coming up as frequently (prefix sum) as others (dfs/bfs), so your chances to identify and practices them are a lot lower. They're not even necessarily hard, but if you're not used to them, they can be a pain in the rear.
In terms of preparedness for tech interviews, I think it depends greatly on the company. If I were to go back and do them again now, I'd feel 95% prepared, with that 5% being due to a certain company snidely asking information theory questions (I won't say who but if you know you know). However, if I were to interview for like IBM, JPMC, BOA, etc. (and likely FAANG's not known for asking DP), I can honestly say I'd feel very confident if I had to do it tomorrow with no dedicated prep time. The interview difficulties aren't consistent, and if you interview with enough companies, you'll find that out pretty easily. It's the gap between doing a pretty straightforward sorting problem versus being asked to use bit manipulation in your OA; it's not that you're less prepared overall, but rather that you're less prepared for a specific type of interview.
As far as whether solving LC is worth it past that 250-300 mark, I think it depends on your targets. If you're looking for FAANG, 250-300 is acceptable. Non-FAANG F500's you can probably get away with like 200. If you're trying to do trading firms, you need to get to that 10-15 minutes for an LC medium point, which I'd say is around the 450 mark; it's not so much that you need the algorithm knowledge, since that isn't changing much, but you need to be able to look at a problem and in 20-30 seconds know "Oh this is a UF problem" , "This is two heaps", "This is graph traversal with XYZ optimization".
Thank you so much, this video is amazing and I needed this so much. I do what you described at 3:19 with every single Medium/Hard problem. I needed this so much, thank you
I always feel like doing leetcode questions on the spot is defently a skill that requires you to maintain doing it. You can learn how to solve lots of em and recognize sort of what structures and algos should be helpful but nailing a problem quickly on an interview in like 20 mins of less requires you to keep praticing it regulary. Which feels like a giant time thief for creativity that could be spent on doing more meaningful things as at the end of the day, its mostly about being able to memorize a lot of things.
I needed this video so bad, your just a living legend for us ! Love you!
This guy is an absolute legend for sharing these “real” tips 👍🏻
Thank you so much for your work! You made my interview preparation process so organized and even hard problems easy to come up with.
And btw the newly added quiz idea is brilliant!
Always love to see your video. Thank you for the commitment and sharing!
i appreciate you doing this video. currently im too burnt out on programming to learn more stuff, but it's helpful to know there's some seemingly easy thing i can do to make more money should i decide to go back.
People think programmers are just gifted with intelligence, they don't see how much suffering we go through until we can solve the smallest of things.

Was looking for information to work at Google, randomly found this channel, wow. I knew I need to work on algorithms but didn’t have a good path, like roadmap, and it looked like a too complex and long way, I was struggling to learn steadily.
Your roadmap made it look so much more achievable. Have 2.5 more years in college, I’ll work and make it, hope I can tell you good result.
You explain things so well that I forget how much work you put in to get where you are today. This kind of videos reminds me of that. Thank you.
you know, 2-D dp arrays are actually just an abstraction for 1-D arrays since i*m + j is unique for all -1 < i < m, -1 < j < n that can be indexed in the array. Same with hashmaps.
DP is all about state. There is no 1d, 2d or whatever. It's just the number of variables in the state.
The fast review is a great feature , looking forward to it!
This is honestly amazing, admire your hard work and commitment!
Great video.
I've been studying for the past few months. And I identify in most of the things you say and you put into words others I only had in my mind.
In my experience and from what you said I highlight:
- Order matters.
- 1 or 2 daily is better than tons a day.
- Repetition, feel free to do easy or mid or hard ones again even if you solve them in the last few months.
- Look and understand other's answers.
you are doing gods word. in the video you joked about being a loser. you are far from one. you put so much effort into rising your competence then put more effort into helping others raise theirs. thank you.
I discovered your channel by chance, and what a chance. Currently in the middle of semester exams. I will start this journey in my holidays.
For several years of programming, I had practically no such problems. Most of the problems are struggling with libraries, frameworks, dependencies and architecture or something like the programming language is not suitable for one part of application. At least in the area of programming that I deal with... Apart from the need for intellectual development, of course, I see no point in practicing solving such problems.
This got me hyped! That roadmap at 2:50 instantly reminded me of a skill tree from RPG games that I want to max out. I started coding 1,5 months ago with CS50X, and using gaming analogies when learning to code changes everything for me! Instant dopamine trigger😮💨 Never tried Leetcode before but it reminds me of XP farming😂
Thats a great way to start. Gamifying educational material really makes them more appealing and I love that.
@@jimhalpert9803 Yeah exactly! Game developers know what they’re doing when designing a game to optimize dopamine rewards. So why not structure your mental picture of your learning process using the same mold as videogames? Makes it much more rewarding compared to the standard process of learning that schools give, which makes everything seem like a chore!
Thank you so much for your hardwork and dedication!!!! I have purchased your Pro Lifetime subscription already, but for the value you offer with all your videos and your website, I really want to just keep throwing money at you because how amazing your work is!!!!

Great effort to create a review section for the questions. Massive respect.. This guy is an absolute legend for sharing these “real” tips .
solving questions and learning algorithms are as healing as meditation. no need for a faang or big tech, it saves my life in such this harsh unemployment period.
I have neetcode and so excited for the fast review feature! Thank you for adding more features!
You're godsent for software engineer preparation, after watching few of your neetcode explanations it helped me understand many stuff which I might've not learnt elsewhere and you also helped me find the confidence to solve any problem, kudos to you man!
The fast review section is a game changer. If and when it's finished for all the 433 questions you have (prefereably in order , finishing blind 65 then 150 then the rest), it will be so much help to get a quick revision during the last few days of an interview.
Thanks again neetcode! I’ve been using your map layout and once I started going with the flow again I understood where my weaknesses were.
This is the best video I've seen regarding coding preparation.
I also started doing "random LeetCode" (well, the most freq asked questions at Google interviews according to LeetCode). After a year and a half I learnt about Blind 75 and Grind 75. Then now after 2 years I found this video with your roadmap graph with the order you should learn topics on. I wished I had seen this earlier as I'm sure patterns would've stack faster in my head!
Thank you for doing these videos and the leetcode solutions, your contributions to the community are invaluable!
Your videos are very useful for engineers who are struggling in LC.
Thanks a lot!
Thank you so much for the roadmap!!
It's helping me focus on a goal
Great effort to create a review section for the questions. Massive respect.
The review list is insanely smart and useful. Thanks!
Always a pleassure when you drop a video, once again great content and advice!
greatly explained, same thing was told by an interviewer with over 1000+ leet code problems solved.
I remember spending so many horus doing LeetCode only to find out that the interviews on the companies I wanted (triple A game studios like ubisoft) literally have nothing to do with regular tech companies. I'm considering going back into it so that I maybe shift out of game dev and go back into regular programming
Don't most AAA ask leetcode? Interviews I've seen have almost been nothing about games and more about trig + leetcode?
@@xx-wp3mq I applied to multiple and currently working for one of them and all the interviews I had were basically small tests to do on my free time.
All along the likes of: build this mechanic in UE and keep the code as clean and optimized as possible.
Then on the following interview they did a lot of questions about the code I did and why did I do it that way and etc. The interviews all felt a way more project-based than the ones I had for non game dev companies
@@prooheckcp Intresting, I've seen a mix bag of interview things online, from "code the mechanic" to implementing a HashMap class. Was this NA?
@@xx-wp3mq It was in Europe. I applied mainly to AAAs in the UK and France

Thank you, I needed this guide video so much!
what is the difference between the blind 75 , NC 150 and all 331 probs ?
This is an inspiring video, I really appreciate how you explain things in your videos, keep up the good work
>video literally named "my brain after..."
>no MRI picture
The most concise video I've watched. @NeetCode rockss!!!
You conclude how leetcode helps you reasoning about unit testing without argumentation, how do you figure leetcode helps people unit testing? Aside of this question I believe things like leetcode are a good addition for practise, but is it really overemphasised by big, mostly American, companies for the mere fact that it's much easier to test on applicants than more abstract concepts.
It helps me because if you press 'submit' before thinking about potential edge cases then you will likely fail the submission
@@NeetCode Ah yes, that makes sense. Thank you.
@@NeetCode 😗that is reality vro
I've majored in CS two years ago and I always compared myself to my fellow classmates as they seemed to grasp programming problems way way easier than me. Even some of them went to Seattle (we're from Mexico) to work for Microsoft. As a result, I always had this imposter syndrome, and while I have landed some ok jobs at Oracle and IBM, I always felt very mediocre.
I'm 25 now and my dream has always been to enter Google or Apple. I thank you so much for motivating me and thousands of people that feel the same way as me.
Do you mean it's better to solve Neetcode 150 again rather than going to 569?
Absolutely, especially if you can't solve many of the problems from the NC 150 list from scratch. It's better to be really good at a small set of problems, then be bad at a large set of problems.
@@NeetCode "It's better to be really good at a small set of problems, then be bad at a large set of problems." Life wisdom right there on how to hone your skills.
@@NeetCode Should I solve all problems in one categori in neetcode them move to other categories? (Should I solve all questions of DP in bline75 before start greedy) Or just do All Easyies all categories then mediums then hard. Also, is neetcode 150 better than neetcode 75?
@@카이트-c8y In one of his videos he mentioned that it is better to solve easy questions of each category first, and then move on to medium, and then hard. That way you will learn the basics of all major categories, since you don't know from which category you will be asked.
As Bruce Le said one day, "I do not afraid of a man who knows 10000 kicks, I'm afraid of a man who repeated the same kick 10000 times.
Thanks alot for contributing! I switched to C++ but I stull use your videos to understand the concept! They are really helpful
"I'm still unemployed so let's solve another leet code problem..."
3:08 This was something I needed to hear. I have spent way too much time bashing my head against problems that I am getting nowhere with. Thank you.
I don't if it's I working in the energy sector or like in Germany but in all my job interviews I never had to solve any coding problems. Of course they asked questions about how I my approaching style or how I would solve something in general. But like I said, I never had to solve a generic "puzzle" 🤔
But I see the values of solving those and do it from time to time on Code Wars
The part usually not said in these videos is that if you're really good at these puzzles, you could land a $200k+ software job on the American west coast, which is an absurd amount of money in contrast to traditional "get a few years of apprenticeship and move up the career ladder" advice. Of course, that was also before the mass layoffs of 2023 and near zero interest rates, so we are in unknown territory.
It is way more common in the US than Germany. Especially when you are experienced no one will basically test you.
I have been looking for something like the Leetcode MC quiz for a long time for reviewing. Simply amazing :) Thank you.
First of all, let me express my gratitude for the valuable content that you have provided. I have a question that may seem trivial, but it is still significant to me.
My coding journey started in 2018 when I began teaching myself without having a CS degree. I started with Python, and then progressed to web development, where I learned Django. Currently, I work as a freelance developer. Although I have considered learning DS/ALGO and applying to big tech companies, my self-doubt and uncertainty have held me back from applying. Recently, I have started practicing Leetcode problems, and while I can solve easy ones, some medium ones take a long time to solve, and hard ones seem impossible.
My question is: Can an individual over 30 years old, without a degree, join FAANG or MAANG companies? I would greatly appreciate your insights on this matter.
Yeah dude, most def.
i m at 300 with 200 mediums, had no more motivation to continue coding ,but hey u motivated me abit maybe so i will go code again
Neetcode, your experiences are really inspiring. I hope to be your colleague one day in the future ☺️
Thank you, Roadmap is awesome. I've been looking for this kind of aggregation of problems.
I just finished 100 problem as per your strategy 🏄
thank u so much for the video and I did sign up ur website thx 🙂
Mistakes to avoid:
- Language
- Solving in random order
- Don’t waste time
- Not reviewing
Amazing video, I really needed this!
I think the 45-60min limit per problem is important, it's happened to me on freecodecamp while doing the JS courses and it's something that is hard for me to apply because I really want to solve problems before looking into the solution.
But some problems as you advance, they become more vaguely explained, with less and less detail and more complex, which can be difficult sometimes to come up with a solution, by the time you read the solution you realize that you'd probably would have never come up with anything remotely close to that so yeah, putting a time limit, looking at the solution and trying to understand it is hopefully good advice.
Making that quick quiz feature is genius!!!
I am glad that I bought your lifetime subscription, whole material is already top-notch , and now this upcoming feature to review questions in Quiz form going to be amazing. I will be really grateful to you if you do this Quiz review feature for all 331 Questions, I know its a lot of work but you can release it in phases. Thank you so much for all your efforts.
Yeah if it gets traction that sounds like a good idea, gonna start with blind 75 and then NC 150
@@NeetCode thank you 😍

Strangest people are those that solve all those LeetCode problems to get into Google, thinking it will be like a "dream job" of sorts. News flash - it isn't. I got hired as L6, Staff Engineer and left after few moths to other company - Google is WAY past it's prime - it's not the company that people wanted to get into 10 years ago. It's full of tragic code, extremally slow pipelines and strange kind of "talent" - people that somehow confuse what engineering work is really about.
My recommendation - stop watching "leet code" videos or solve those abstract problems - start solving real problems, in the real world - because this is what EVERY business is built around.
Finally someone who understands. Thank you!
I don't know if it's a US thing that they are so obsessed on Leetcode problems. Where I live you basically tell them in an interview that you know their stack bla bla and then you start working with a probationary period. All they want is experience with the stack. When you tell them you solved 200 leetcode problems they will either laugh at you or ask "What is Leetcode?".
One thing I'd add about language choice is that picking a language without built-in data structures in the standard library makes it impossible to solve certain questions optimally without literally needing to implement the data structures yourself. For this reason, I moved from TypeScript to Python for this kind of question...!
Love the road map! Don't think it's entirely crucial to study backtracking prior to dynamic programming, but a recursive thinking process can certainly help with solving dp problems.
"There's no shame in looking at a solution, as long as you can understand exactly why it works." - NeetCode TS: 3:40
Honestly what is missed with your leetcode problems is the thought process you went thru when you first solved the problem and the actual time it look to solve it. So many of these videos make people feel like solving these are easy when they are not.
sometimes you can spot some of neetcode's recent submissions and it gives you a piece of the whole picture
My important take here: "You will never feel ready". I needed this thanks
