- Coding interviews are hard. But why grind LeetCode, study data structures and algorithms, and read Cracking the Coding Interview when you can simply "throw a hashmap at the problem"?
This video may or may not be based on a personal experience...

@@AndrewCheetah no way!
The code looks like Java, do the questions in your area for Java Developers really look like this? Im from Poland, but I often aslo apply to international companies, and those mathematical problem solving seems a thing of the past here , assuming we are talkign about bussiness software. 10 years ago it could happen (i remember when Codility was very popular here, many problems were a variation on quicksort...) , but nowadays its usually just a lot of knowledge checking : some basic Java questions,.Java 8 constructs alwys, design patters, frameworks (Spring , hibernate etc.), webservices,SQL and no SQLdb , javascript, coding theory SOLID etc. , maybe they give you some code to review. I actually think its a better approach because that relates much more to what you will do at work with bussiness software. Unless you apply for games software or some niche science projects, I guess, but its rare with Java.
But as to the point, yeah, the mutistage interviews are really frustrating:). You tought you made it , but it turns out it was just the mid level boss:)
Did you pass the other interview 🙄
@@MillandeepSingh im pretty sure i passed because i got the optimal solution, but didn't get the offer 😥
Bombshell: they're not actually interviewing you, they're just stuck on a code problem and want a free solution! 🤣
haha i've seen startups give take-home projects that just look like work they need someone to do for free😂
lol, they need help solving two sum for important business reasons. nobody else has been able to solve it to date
XD
LOL
No shit this is actually kinda what one of the questions I was asked for my current position was - he basically just wanted my input on how I might go about solving a real problem he was working on, it was actually pretty neat
"Do you think you could make it faster?"
"Nah, I'm good"
“You’re hired!”

Your pfp fits ur comment perfectly 😂
Lmao

In my coding interview, I realized I could use a hashmap to solve one of the tasks. Then I remembered this video. I smiled and became less nervous. I passed the interview. Next week is my second interview. It is for my dream intern position. Wish me luck, guys
great, have fun making apps to make some jewish guy rich :-)
HOW DID IT GO

I got hired for my first job in an IT company on my first try a few months ago. The interview guys were very chill. The HR asked about my life experience s and my side hustles along with studies. The technical guy asked questions about Java, Android development stages and later on, Angular (which I didn't know much about). Moved to a new city now and the working environment is great. Such interviewers are awesome.

What was in your technical interview?
And what's the name of a company?
Which role did you apply for?
This was my real experience, started interviews past 2 weeks rejected by 3 and counting. Each rejection is an experience and become better I am sure I will get through this phase.
Glad to inform got 3 offers and played salary matching game. I got my expected salary but not landed in tier 1 companies. I will continue preparing leetcode and land in tier 1 company. My salary increased more than 30%(TC - 210K).

i think interviewing candidate just based on algorithm solving is just stupid. In work 90% of employees will never encounter this. And things you want to test are untouched.
@@opatechnus That's a strange reply to the root comment.
Anyway, if it's a good interview, the algorithm skills aren't meant to be a reflection of practical work, but rather, it demonstrates fundamental skills that are required to do good programming in general. A typical coder shouldn't spend much time optimizing, but they should at least not write code that's absurdly inefficient, and avoiding those pitfalls should be so natural that there's never even a conversation about it. That's why these kinds of technical questions are seen as a bare minimum for hiring.
Sad thing is I understand a bit like I can read the code and know what it’s doing but I didn’t do hash map or at least do it enough to remember a damn thing on it
I was literally asked the same question that I had solved the previous night, word for word. I deliberately started writing a naive approach, then halfway through that, pretended like I had just got a revelation, commented out the naive code and barfed up the O(n) solution like a freaking genius. Code worked.
Didn't get the job.
LOL good try tho
damn you should have
@@hebariaz6134 It's not very difficult to tell when people act like they don't know something. The interviewer is generally more concerned about the thought process and ability to solve a problem they don't already know the answer to.
Why would You do that though?
@@kekag yep. Theyre not testing memory. If you’re going to pretend you havent seen the problem (which is a good strategy) you cant just “have a revelation”. Sell the thought process. Write up the pseudocode for the naive approach and then say there’s definitely optimizations that can be made. Sit and think. Think aloud. Walk through logic that would lead to those “revelations”
I'm a german software engineer working at a big company developing MASSIVE software (over 80 million lines of code) and i've never had a "coding interview" lol. Also i think that understanding problems quickly and knowing where to find the information you need is a far more important skill than explaining a sorting algorithm when you've done nothing else but learning them for the last couple of days. When you work and don't refesh your sorting algorithm knowledge you forget 95% of it after a few weeks anyways and even then you can just google it. Not something to differentiate good coders from bad coders imo. Using the best optimal runtime algorithms possible is pretty important but as i said.. you can just google it, it's just important to have heard it once and to know that it is a thing.
The funny part is, for 90% of the use cases, you're doing it wrong. It's the same thing with security, don't reinvent the wheel, your wheel won't be as round, the stdlib of any language you're using has a much better sorting algorithm than you will be able to make (they actually use a combination and heuristics and can even run in parallel)
Yes sir, I think you're right.
yeah but in germany its hard to get a job without a degree, in the US you can at least do that with one bootcamp
hello sir can i talk with you
100%, if you are on your third or second year of your degree you probably are going to remember this better than somebody that got the degree 7 years ago and has 10 years of experience xD
This was actually just helpful for me to have some different ways to look at this problem! Thank you!
Dude when the interview started I felt like I was the one being interviewed. I felt that fear in me
😳😳 coding interviews are so nerve wracking that they can be felt through a screen 😂
I share that feeling
@@nicholast your video just scared me for my future , I m gonna start my term in fall this year in computer science major
@@AmanDeep-rk6je Don't be scared. There are other companies besides Google etc.
Cam??
I first saw this video a couple of years ago. I had never solved a leetcode problem and it was all gibberish to me.
Now, every single thing makes sense and are intuitive solutions. Never give up, keep up learning and trying with your Leetcode!
can you tell me how you started leetcoding... it actually makes no sense to me and I am always afraid to start
I remember the first time I watched this video over 6 months a go as a CS freshman I didn't even know what a HashMap was much less anything regarding time or space complexity but now I have been pleasantly surprised that I understand everything in this video now
me too, but I sure as heck cant converse comfortably like that XD
This is me now, I hope to be back in 6-9 months to see the progress that I will have
Give me 6months
Could you please help with materials or a guide on how to learn these things in their order of
importance and according how I will need them to advance my learning.
I just started out and have not being making enough progress because I don't have a streamlined
learning pathway to teach myself all the necessary things I need to become a software engineer.
Please kindly help with resources if you can, I can't afford college.
@@josephubi9096 Hey, sure. It really depends on where you're at currently and what you are trying to do within the field of computer science; whether it is web development, game development, data science And AI, or becoming a back end web developer.
However regardless of what you want to do, having a good foundation is very important. So I'm order to learn the basics of how to program I would recommend learning python as it's quite beginner friendly, although personally my first programming language was C and looking back it was definitely a great foundation but extremely hard to pick up at first. So in order to learn the basics of programming with python I would recommend the course Python for Everybody (you can find it on Coursera, edX and even RUclips) because it will start off slowly introducing you to simple topics but by the end of it you will know how to use python to parse a web page and make requests to an external API.
After you learn the basics of programming with python, I think you should switch gears and learn a bit of web development by learning html, css, and JavaScript. A good resource for that is freecodecamp.org or even the Odin project which you can find online. Once you do that you should have a good feel for the basics of programming. Reading computer science textbooks can also help too and then you can decide what you would like to build next. I hope this helps you.
In fact, here is a link to a GitHub repository that gives an alternative line of courses for you to take: github.com/ossu/computer-science
I own an IT company. When we take interviews we allow candidates to use Google or any other resource. We hire people even though they failed technical. The most important thing for us is willingness to learn.
Hire me then lol
Can I work for you?
I'm so glad to hear that XD
You’re awesome
**Gasp** cool companies like these exist?!?
Throwing a hashmap at the problem when you're stuck is actually pretty good advice, it's a powerful structure that will save your ass many times.
facts
What is a hashmap?
@@titord6031 a collection of key-value entries, also known as just map or dictionary.
@@titord6031 hashmaps are like unordered sets in the mathematical world. Lookup times are O(1), but only unique key values are allowed.
But you have more data plus you need to hash everything right?
The main thing to take away from these interviews is that you will always be questioned on your solution to the problem. Invariably you will be able to improve it to some degree, the interviewer just wants to see if you know how. From my experience when I didn't know something it wasn't a bad thing, it was just a way to find the extent of my knowledge. I got good feedback about my solution after the interview and got the job. So when you are in this situation be calm, do the best you can and if you don't know something then don't worry about it, worst case scenario is you don't get the job and you never see that interviewer again.
This is way of showing people how tech interview works with kind of melodrama is brilliant idea wise, appreciated 👏
As an interviewer: This is 100% accurate. However, don't waste time coding the slow solution. It's fine to mention it, but if you know a faster solution go straight to that before coding.
nice
@@dhruvakhera5011 nice pfp
Came for this comment. Put your best foot forward, I'm looking at you as a complete candidate who tries to solve problems the best way you know how. Much better than a fake crappy approach just because you know the "can you improve this?" question comes next.
While I agree with this, that was the interviewer's fault for asking him to code a brute force solution instead of asking for an optimal solution before he started coding.
@@mdouet he never said brute force or slowest, the interviewer just asked for a solution

I’m new to coding but I honestly doubt unless you’re going into a very lucrative role they would ask this type of question under pressure. As others have said, no decent code is produced in 5 minutes and certainly not under pressure.
Don't stress it luv, plenty of opportunities to learn and do not be affraid of failures. Simply learn from them and continue your journey :)

So the trippiest thing is one year ago I watched this video when I was researching pursuing a career in coding, and now one year into learning to code I am slowly learning about Hash maps, and watching this video again, I actually, to an extent, understood what you were talking about!
I thought it would end like "Thanks for fixing our coding problem. Thanks, bye!"
that would've been good 😂
Exactly what I was thinking!
If solving one problem for free for them would be annoying, imagine working for them making maybe tens of thousands while they potentially make billions off of your work, and you're not even allowed to work anywhere else
I always imagine that’s how these go. You’re actually solving bug tickets for them in prod.
Wow so many likes! Ty guys hah :D

Dude! This intro is priceless!!! Just getting into web development wanted to know what coding interviews are like and this is the first video yt recommended!
This is a great video ! Not only funny, but I actually learned something too.
I wouldn't have thought of that hashmap solution
I know this is supposed to be for entertainment but as a CS student this just makes me wanna die and dread having to do an interview like this lmao
Bro I thought I was the only one 🤣😭
I'm only freshman and worries always filled me
Only FAANG does this. For Junior positions, smaller companies ask you more about logic, some questions about CS knowledge like polymorfism etc. They also ask you to solve real-life problems so they can see if you're willing to learn and if you actually ever wrote a line of code. Don't worry too much ;)
for junior engineers i recommend practicing easy - medium problems leetcode (they have filter for top interview questions) as you work on harder problems you will learn more neat techniques. don't wait till you graduate, especially if you're aiming for top companies, though if u aim for small companies I'd still recommend you practicing in case you change your mind (never a bad thing to keep options open).

Good job Nick. Always a easy way out of all the problems
Software engineer here - I didn't follow all of that.
I have been writing code for almost a decade now across several large companies using a variety of frameworks and languages. All I can say is that not once in my career have I ever had to solve anything like this.
I've also hired developers in on my post as a dev manager and scrapped the tech test as my first move. I care more about their ability to learn and attitude than how well they can remember academic-type questions and answers. They need to understand code and how to solve problems, but I'd rather have a someone on the team that can pick that up quickly and can demonstrate some fundamentals than someone who can rattle off 'coding exercises'. The reality is, most jobs are bug fixes and you'll likely never encounter such BS
You've never worked for big tech like Google, Twitter or Facebook. I agree with you. Im a senior software engineer for about 7 years and a database administrator before that. When I interview, I throw out a couple feelers to make sure you can code but never anything like this. I usually stick to past experiences and let them know what our past current and future projects might be and ask them for insight on how they would handle some of the issues I've had or foresee. I have never had a bad hire using those methods (I've hired 10 developers in my career all have been with me over a year and did fantastic work)
@@USFighter I'm 27 years old, haven't held a job in years and got a bit lost in life. I feel like I want to go the software developer/engineer route. Where would you suggest someone like me with near to none experience should start?
@@GrantH2606 first off, what are your interests?
@@howardbaxter2514 I do not know what my interests are career-wise, I just know labour isn't it. Idk how I'm supposed to know what my interests are...
@@GrantH2606 Ideally, you’d find a career in something that interests you. So what do you like doing? How do you spend your free time? If the answer is “playing video games,” it’s unlikely you’ll get a job doing that, though it is possible, but maybe you want to get into video game design. You have to do a lot of research, find RUclips videos on careers in fields that interest you, and see what the jobs are like. I know people in their 50s that still haven’t figured out what the hell they’re doing. Try not to stress about it too much, and try different things if you can.
I’m terrified of the coding interview. I’ve always had horrible performance anxiety, once someone’s watching me my mind goes blank. During a practice coding interview with an instructor he had to remind me that for loops are a thing 😭
I feel the same thing 😭
I was in a pricey bootcamp and didn't have much further to go with it. I wasn't enjoying it at all. Learned to hate coding when trying to make it a more serious career. Once I found out how the interview process worked and what to expect I was done - dropped out and went and changed careers again to something else I like better. Happy I did! Landed one of my other dream jobs.
Just practice with someone (who codes) watching you code. Practicing control of your anxiety and mind state is half the battle.
@@RocketVet What did you change too?
@@Pulsed101 I hold certifications in personal training, health, coaching/CBT. I went into social work doing life coaching classes and case management. Feels great helping people again!
I've been a software developer for 16 years. I've been through plenty of code interviews and I've almost never given the best solution. Know why? Because nothing I've done of any quality is done inside 45 minutes. I just don't stress the first pass. If they're looking for perfection after 45 minutes, they're just looking for people who probably already got the correct answer online beforehand.
they just wanna know if you've been grinding your leetcode 😂
I think I will just say that on my next interview, actually. Thanks!

I was able to move on to the next round of interviews because of it, and then later on I eventually got the job.

this was actually a solution that was desired from me once: the best answer was to generate a lookup table beforehand, and just use that in the live code.

use a hashmap, lol key = input, value = pre-programmed desired output.

@@electrenator5601 that’s completely wrong, like everything you said 1. Java is a lot more complicated than python and 2. Learning another programming language is like learning another language you should always start with the one you want to end up using
@@jabjohn3784 No? Learning another language once you are profecient in one is like a 2 week struggle. If you cant get used to a new language within the same paradigm within a month at most then you clearly do not understand your current language.
@@perhapsso1909 Ok I’ll agree on that basis but Java is a lot more complicated than python
I’ve been debating about going into coding for a couple months now. Thank you for this u-turn 😂
nah u should try it
😂😂😂
No the u turn 😭😂
I've been working as a programmer for nearly 10 years and I've never had an interview like this. It's an extremely broad field, it isn't all like this.
@@lalala-lt8fe let me guess you doing front end?
Lol, when he mentioned to throw a hashmap at it I immediately thought back to one interview question I got where I bongled it because I didn't think to use a hashmap to get linear runtime until after the interview was over and it was this exact problem. I hate code interviews for the same reason I hate oral exams. If you don't immediately know the solution you're just fucked and if you're the type of person who gets nervous at oral exams you're just at a huge disadvantage compared to someone who doesn't get nervous. I mean, it's not like you'll ever be in a situation at your job where you have five and only five minutes to conjure up and code up a solution to an algorithm. Anyway. Fun and relatable video.
I'm glad I've been working at the same company since I graduated 22 years ago because I would not be able to code up something with someone watching over my shoulder in an interview setting. But I do agree... whenever you're stuck the solution probably involves a HashMap.
I love how the guy just awkwardly walks away without further explanation, even though the person he was explaining to was clearly still confused. And he literally is walking to nowhere.
My name’s NINO
I came for a quick joke and ended up learning about hashmasps and having a Big Time Rush nostalgia trip. Sub.
love to hear it!
Good. One more video to show for my students about why Data Structures are maybe the most important topic of efficient Software development
Just saw this now and this is making me motivated lol
Interviewer - MAKE A TIME MACHINE
ME- What ?
Interviewer - Too late, *Rejected*
And from all us coders out there, here is the real answer: "No problem sir, let me just google that for you!"
😂😂😂
and Stackoverflow xD
thanks for advices 🙏
I felt dumb af because my brain started kind of blurring some of the stuff you were saying, but hearing pairs and my first thought being HashMap and it coming up actually made my day. We take these wins, no matter how small....
Lol, at least you did better than me, up until I saw this video I only knew Hashmaps as Dictionaries
To someone who just finished making the snake game, it's too much
Don’t give up.
Brooooo i just got done with html training😂
@@onedumbsloth5029 I am not sure I can consider HTML as "programing". . . By definition it is but IDK. HTML seems to be fundamentally different than say Java, C# or something else. Would say it is like "Anyone can build a house, but not everyone can code a program to build the house".
@Nicolás Agustín you and the guy above must be fun at parties
@@do.xuantung No at this point it's almost a meme... It's like in the real world... "I built houses with a big crane", "I build houses with two small cranes and a crew to lay the bricks" and "I build houses out of lego"
I was expecting a joke of a video, but this was actually extremely helpful as a CS major.
Wow this is so accurate, ive had like 3 interviews for the same company before finally getting the job.
The best tip I could give is to not be sad if you dont ace your interview. Always try to learn from failiures and never say you know something that you cannot explain.
:)
Good luck
Thanks 👍
Just fyi, there is actually a trade-off between the 2 solutions; neither is more optimal than the other. The second solution, even though faster, takes extra space. A better script can be asking the clarification question first ("Is the array sorted?") and then propose both solutions depending on different conditions.
That part where he didn't know what to do next and just kept saying "uh" over and over really hit home, lol.
No idea what anything you said meant but I was very invested into the video. 10/10 acting, would recommend
Lmaooo thank you Jason :)
As an interviewer, I have never asked a question like this, I am happy when they show basic problem solving capabilities and are able to google. Of coarse I don't work for Google or Microsoft either.
Lol. I really like these videos. This is exactly like the engineering interviews. Especially the oh I just did this problem last night but I will pretend this is my first time seeing it.
I wouldn't give him a second interview because I said you can assume there will always be a solution but you wrote an Exception and told me what would happen in the event that there was no solution. You can't follow directions, not FAANG worthy XD
you can never be too safe 👀
If some manager says it will not happen, it does not mean that it will not happen.
@@michallasan3695 it's like in my "software engineering interns be like" video (don't wanna spoil it, but you should check it out if you haven't already :))
What would you have done instead? There has to be a return or a throw, otherwise his code won't compile smartass.
@@taaihone6881 I'd put there different message, like: "shouldn't get here" and clarified to the interviewer this was added with the only intention to make the code compile.
I had the "throw a hashmap at the problem" awakening only yesterday. Code works in mysterious ways.
2 years ago when this video first came out, I had no clue what he was talking about nor the problem at hand. Now I can't believe I can now actually understand everything that's being talked about in this video!
That very famous two sum problem from leetcode. haha. I would have directly jump into the Hash Map for sure. Thanks bro for teaching me this ninja technique. :D
"Could you make it faster?"
"I'm sure we could, let's discuss it during tomorrow's stand-up; I'm sure the team will have some input. After all, this won't go into production for 3 months, so we have lots of time to refine it."
“That would be a cross-functional effort requiring 10 engineers and 4 weeks. Let’s keep it in the backlog for now”
Yeah and after the second interview they just ghost you out and you never really get to know why. Been there so many times
f in the chat
@Elon Lothbrok, this one hits hard lmao
Really? F**k. Even after learning so many years of coding we might fail at this point 😑.
I think i hate this most , I had a few interview when im pretty sure i answered like at least 90% right and they still didnt hire me and got back with no or a weird feedback. IF the feedback would be reasonable , like what you did wrong, what did you lack, it would be so much more constructive and understandable. I remember one company after the interview as feedback told me "my talents lay in other direction" Wtf lol. Should i start ice skating or something, even tough i was professionaly programming for 5 years already at the time. Screw them.
I got ghosted because they had intended to give the job to someone else within the company and didn't tell the recruiters.
Just started learning but happy I understood most of this context tbh
Nice keep it up 💪
Loved the Big Time Rush Outro at the end 👌🏼
Jokes on you, next interview is a gauntlet with at least 4 other engineers. Prepare to have your entire evening consumed only for some rando in QA to not like the way you wrote a given in one of your unit tests and eliminate your application
I usually don't bother about it. I just keep looking and hope for a more practical engineers that ask real world scenarios on how im able to handle it and give a solution.
😳😳
Unit tests?
@@donventura2116 Oh yeah.
Well that's encouraging 😂
That “hmm good question. Uh, I, uh, well instead of doing what we did…” was one of the most relatable things I’ve ever heard. I don’t do coding anymore since I’m ass at it and straight up don’t like it and this video was so accurate
😁 I have no idea about coding but enjoy your video, also share this to a friend
who is learning to code and going to interview for boot camp or something, not sure
This video actually helped me in an assessment i got stuck and threw a hashmap at the problem and it worked
_*5 minutes later *_

We greatly appreciate your time and we hope that you continue to follow our posted job opportunities in the future.
Someone's been rejected a few times before
like this
tbh I would rather them fully vibe check me & read every single 'less than ideal' comment from the interviewer.
like "Honestly, this guy uses the term 'ostensibly' & 'thus' far too frequently. I will quit if you hire him on my team" & being somewhat petty, is something I would prefer to corporate nice-speak.
Oh btw for anyone who reads this & thinks "same": I have had good luck in getting real feedback by reaching out to interviewers via linkedin or github (note: not their @work emails), but I am careful to not be weird about it lol
I'm currently studying for my exam in algorithms (mostly time complexity). Thank you for giving me shortcuts with this video.
That's pretty advanced knowledge from where I'm sitting
Nice video
Rewatching this a year later and actually understanding what’s happening makes it even funnier
