Although it was his interview, here while watching, I am sweating lol. Great session!
Lol true
I too have the same condition
Same bro.....bhai do teen baar to meri bhi phat gyi
True bro
True brother......😅
Though his few answers were wrong but his confidence was on top, gotta appreciate him!
Shukriya bhai
I am not hating, but most of the answers were off, cause he doesn't have the intuition behind the theory, that's why he is confused so easily. He has studied some form of "what the method says it does", but has no idea of "why it happens/why it works".
he is in 3rd year and he has a lot to learn, but certainly on the right track and with the right pace.
After watching this interview I am feeling nothing I have to revise lots of things Very good effort by the organizers and by the Manish
* skweness measures how much your data is distorted.Right skweness means positive skweness and the mean will be greater than the median. To remove skweness u can apply log over it to normalize.
* Standard scalar normalize the data as x-mean/STDdev. While min max scalar make it betwee 0 to 1.
* gini impurity = 1 - sum(p(y)^2)
* n_estimators=30 can reduce variance more..since rf generally reduce variance...so there is a chance that it can underfit...Generally it depends on data.
* Machine learning over deep learning when we have less data and interpretability matters for our model.
* Activation functions like relu,sigmoid etc introduces non linearity to the network.
* We can SGD with decay learning rate if we want to reduce it over iteration
* Another reason for up and down movement of loss can also be due to exploding gradient problem..
Perfect. Thanks for letting everyone know❤️
Hi bro I am done data science course can u suggest me any project to show in resume
Really awesome interview. Thanks Krishna and Sudhashanu for wonderful questions. Its helps lot for me. Its clearly says even myself need to improve
Even though he is a fresher, he is performing excellent with confidet with out tense or nervous really very good
Got to know how complicated the interview is.......and at the same tym got the structure of interviewing through this mock interview...good one!
After watching this interview I realised I need to do more hard work and much practice..
The interview questions are good and even the guy who is being interviewed is performing with confidence. But what I have a suggestion is, even though this interview had good questions, the way of conducting a professional interview should not be like this. An interview is not meant to stress the person who is being interviewed and confuse him. It is the responsibility of the interviewers to conduct an interview in the most peaceful calm way. We are humans and mistakes would be answered by everyone, anyone can be wrong, but the mistakes should not be pointed out in the middle of the interview, which inturn will drain the confidence of the interviewed guy. This kind of attitude is not expected from a professional interviewer. It becomes the responsibility of the interviewer too that if they point out a mistake they should correct the mistake by letting them know the concept or the right answer. Honestly, interviews are meant not to stress or pressurise the person or the people watching this mock interview. So it would be better to conduct such interviews in a modern way. Research the interview rules and post mock interview videos instead of pressurising the freshers. They do deserve a respect for their hardwork from the interviewers, even if they are not getting job atleast behave to them with a consideration as they are humans and not as a machine learning model trained with some stress parameters.
Manish is really great guy and now he is so improved. Great to see this.
Ayee. Thanks. Revisiting the comments xd
@@manishsharma2211 Hii, hope you're doing good. Would you like to share where you got the job?
One thing is he was quick in answering those unpredicted questions, I would have been sitting like dumb and thinking a lot.
May I know what are you doing these days?
@@champstark8974 I am currently employed in Bosch as Software Engineer
Great effort, Krish. You are helping a lot of intellectuals.
Literally I have no idea of data science.
I'm from CSE background.
I watched full video of this interview.
I was amazed with his confidence on answering questions.
I like the candidates interest.
Feeling inspired🤘🧡
Thank you dinesh❤️
I just realized that I need to work even more harder in interview aspect :0
25:51, tanh is more computationally intensive than sigmoid, see the formula for both functions, you'll notice that the exponential term appears twice in tanh, making it more difficult to computer.
Also sigmoid are not zero centered, this makes convergence slower
Sigmoids and tanh functions also saturate often, making the gradient of the activation==0, which stops the learning process for neurons
This is pure gold @krish @Sudhannshu great questions and beautiful knowledge drilling thanks a ton . @manish nice confidence and effort.
Thank you brother :)
@@manishsharma2211 Hi Manish! Can you please tell me whether you are working now and in which domain?
Heads off to his confidence even after complex questions
Thank you gagan
Bro did you got placed in your placement pls tell@@manishsharma2211
Congrats Manish, 👍
Excellent initiative Sudhashu and Krish.
Thank you brother ❤️
We really wish for more interviews like this ....
Thank you very much
Like your confidence manish and I hope after watching this video after three years,you will be improved now.
Hey thanks. Yep, I hage improved
A Great Reality check for fresher, Thanks for sharing!
Very informative video 👍 Thanks for sharing.
Good job manish....for a fresher
Sir if you can please start this series .. it will be helpful for us( even if you can start paid one it will benefit every Data Scientist aspirants
Manish bhaiya grt job..🔥
-a junior from ur clg.. :)
Thank you ❤️❤️
Even the interview questions are okay to handle but main difficult part is to get a interview call for ml and data science . There are hardly any opening for this role compared to sde role..
Sahi kaha
completely grilled him
this motivates me to study more
Yep. I was grilled badly , but i am stronger now😀
@@manishsharma2211 Awesome! All the very best for future :)
@@tintintintin576 Thank you Sharma ji :)
@@manishsharma2211 can you please help with the material ? Basics are really tough, and I can't get those altogether.
@@manishsharma2211 7:40 here the answer is using 'median' or 'transforming into standard normal distribution'? is it right? pls tell me i dont know
I didn't know that data science interviews were this easy.
Great confidence manish ! to face such interview is a big deal
Thank you Samriddhi 😀
We shouldn't only study but also FEEL it.
Yes
Very helpful but scary.. Thanks for sharing.
Amazing Manish!! So proud!
God bless you more dear.
Thank you jerlin 😊
Hi jerlin
Hii
I'm vamsi
For skewed data , we use logarithm, exponential,
Good Job Manish bro U tried your best and almost nailed it👏👏
Yes. I tried my best.
@@manishsharma2211 tommorow I will attend vartiual interview plz help me bro iam affraied iam a fresher
I think the boy was nervous as he is fresher ..he should've just strengthened his fundamentals ..it's a mistake everyone is making..omitting basic things and going for advanced things like DL and their algorithms..big mistake..
Guys, Please do a video on the Story of a person without a degree become Data Scientist. I don't care whether it is a Successful one or not.
17:24 he is right on bootstraping aggregation and Cross validation different Why they say no issue. He is already answer correctly.
tomorrow i have my interview and for me this video is full of tense... plz wish best for me
How did it go ?
For anyone who wants to know:
Iterator is normal loop.
Generator is loop with the yield keyword.
(Of course you need to elaborate these two lines.)
thanx
Sudhanshu and Krish, you are really doing a very great job. It is very usefull for us
Yes. They are the best❤️
@@manishsharma2211 Hi bro. What are you doing now? Cracked any interview? Kindly share your experience
Hi Krish, these interview sessions are really hleapful for fresher, thanks for these.
I couldn't quite catch up the question where you asked about the splitting the dataset into train and test. could you please put up the question here?
Is it true that the dataset is split into testing and tarining with respect to both Rows and columns?
28:24 Maybe something along the lines of AdaGrad ? Adaptive Gradient kills the learning rate for features that get updates frequently.
Then moving from AdaGrad (by pointing out the obvious disadvantages, ki learning stops after a while) point out at RMSProp and Adam
By watching this interview , i think i will never gonna get a job in data science field .
Guess what, i got .
@@mitdasondi2171 well done man..it seems it took just 1 month to change your decision..
Fresher ke liyeee itnaaa jaada padhnaaa padegaaa iskooo dekhhh ke darrr laggg rahaaa hhh merokooo tooo abbb
Haha, aisa kuch nhi hai brother. Bus confident raho, baaki sab place pe aajyega
Hi Krish ,Can you please take interview of experienced candidates as well especially for deep learning (image processing and NLP)
Kuch jyada hi roasting for a fresher
16:44 In bootstrapping technique, we pick samples with replacement and in cross validation, samples are picked without replacement.
Bootstrapping is an up-sampling technique, whereas cross validation is used to measure model performance.
Bootstrapping picks datapoints from the dataset, with replacement i.e. that the same datapoint can be picked again too.
For k-fold cross validation, we divide the data into k-folds (k-partitions) and iteratively take one group/partition as a test_set and others as the train_set. We evaluate the model for each iteration and the accuracy is the mean of all iterations.
His Confidence damm❤🔥
This guy really need to clear his basics first. This was me, 6 months back.
I will try my best sir❤️
@@manishsharma2211 no issue bro, it happens with everyone, I am also learning, everyone has been once at your level. Just keep on learning👍👍👍
@Debjyoti - can we connect? I'm also learning
@@manishsharma2211 all the best bro
Love you dil se❤❤
Wow man this fellow is in 3rd year.....for sure I was nothing at that time....
Thank you sir ❤️
For right skewed data we can perform some kind of transformations(log transformation) on our data so we can make our data normally distributed. Sir please let us know if I am correct.
Got it had to be very clear about the topics which u say u know . It does not like i have studied this much of topics , u have to be very clear what u telling u know.
such a great learning experience
This is brilliant!! Thank you sir🙏🏼 it will help a lot
Cringe but he is a fresher.
bhaai saaab if its a demo of interview that means i have to learn a lot again
Hello sir i was preparing for banking exams bt now i am thinking to make career in data science...i really found it intresting...i need your guidance plzzz help me out i want talk to you
Don't waste ur time more than 1 year or 2 years on government jobs.
If u waste more than 2 years ur not eligible to software jobs unless u put experience.
Don't prepare for clarical jobs
Prepare for group 2 level, po, group 1 job other wise leave and join in software immediately
great interview🔥🔥🔥\
Manish bro great job 👌👏👏
Thank you :)
it's very helpful....thank you sir
Manish has some talent at bsing
Hehe😀😂
loved it.
This interview is in reference to placement or internships?
Everything is good but next time please wear a proper dress .dress code is important
I am Data Science student. How can I get selected for this kind of interview? Please inform.
You have to send your resume to krishnaik06@gmail.com
Very wrong answers
i did my ms in data science still have far less knowledge then this guy .
Same
Do dress codes matters in live interviews?
Great!
Thankyou so much for this!
After seeing his interview iam not going for Data science
Actually he said right for difference between bootstrap & K fold the first time.
Yes :)
Bt that's there way of confusing u guys so that u can double check n they can check Ur level of confidence or grip on subject
@@nikitasaraswat4574 I was about to repeat the same thing, but they jumped onto another question
live chat is not available for this video..where can I get the answers , can anyone help?
sir data scientist ke liye ko job hai kya please
Normalisation is all value should be in same scale...
Sab aata hai par kya aata hai..😢
Great session
I don't know why.....but my heart racing......😧
You should imagine my heart beat 😅❤️
@@manishsharma2211 😁
Looks like the candidate seeing somewhere written answers and descriptions and transferring the same to the interviews.
Hey Amresh, I wasn't looking anywhere. It is just my tendency to look around while thinking about the answers.
Cheers :)
@@manishsharma2211 hey man, can I ask you a question?
@@harishnetam502 Sure
@@manishsharma2211 too late I forgot 😅
Bhai job lagi kya kahi @@manishsharma2211
Thanks for uploading this video. This is the direct proof of how people who do not even know the basics of mathematics and statistics are building the machine learning solutions. Such a dangerous world we all live in. I haven't seen a person so wrong in every answer he gives. He should rather focus on getting the fundamentals correct than worry about machine learning.
he is in 3rd year and learning. dont drag people down. i am sure he will be a much better candidate after his grad.
@@theoutlet9300 Perhaps I was misunderstood. I am not belittling the poor guy who is being interviewed, but the fact that there is no focus on getting the basics right. Of course, this is the problem with whoever is teaching him. All these short term MOOC courses would guarantee you to become a Data scientist without training you in the fundamentals. Tomorrow they might come up with a short 3-month course on how to do open-heart surgery with 12th-grade biology knowledge. The world is indeed dangerous but not from the gullible people who get trapped in this money business but those who themselves do not have a formal background and then train other people.
@@sachchaadmi6152 I would like to say , i have not taken any course !
If there is a mistake in me , it is only due to me !
Don't blame the courses of someone else 🙌
@@manishsharma2211 bro don't blame yourself too, jab fundamental or basic clear karane wale teacher or institute ke faculty support na kare toh bhai khud se search karke dhoondh dhoondh ke mehnat karte hua padhai karni padti hai or ismein time lag jata hai or sahi mentor mile toh sab jaldi cover ho jata hai, mujhe 1 saal ho gaya hai par mere basic or fundamental cover karane wala koi nahi mila or khud se kar raha hoon jitana samajh aata hai kar leta hoon par itane questions hai koi experince ya mentor mil jaye toh hi clear ho, har baar galti student ki nahi hoti hai
7:40 here the answer is using 'median' or 'transforming into standard normal distribution'? is it right? pls tell me i dont know
Yes. It was actually log transformation
Thanks Krish
Good initiative
Btw good idea but did Manish give permission to record this video? If not, he could file a defamation case for uploading his interview on public channel. Hope that is taken care of!
This is not the real interview. This interview was specially made to be live. This was not recorded.
Thank you😀
@@manishsharma2211 haha okay, good idea to have a mock interview.
can you please tell me the company name
@Krish Naik the link to the telegram is not working
Great sharing
Is he selected?
good stuff
33:07
Speed vs velocity
tora abhiyo tak 1 million naa holau..kochi tu padhayite h..
I dont know but i am laughing in the whole video
Slope gives rate of change 😏😏😏😏😏😏😏😏😏
😂😂oops
Manish I really like Ur positive attitude
Slope shows the amount of change of Y variable with respect to x variable
Manish bro am in second year I want to talk with u bro and follow u

Is this real interview😰
No dinesh.
All the answers are wrong. Just over build up by this guy 🤣🤣🤣 Interviewers spot out the knowledge of the guy in first 15 mins itself.
Is data structures important for data science... Y or no
Y
1hr interview 😭
