Most Uneducated/Dumbest Thing You Have Said In a Data Science Interview?

An actual dumb thing I said was at my first Data Science interview at a top tech company here in Bangalore. Interviewer asked me about my projects, and me being unpolished, I said that I had done a regression project. So he asked me how did I measure whether the model was "good".

I said that, "The accuracy of the model was high"

Interviewer responded with, "...You know Regression tasks are measured with MAE/MSE/RMSE and not accuracy, right?"

Lmao. You live and you learn. 🤡

I was asked about Gaussian distribution and I said I never heard of it and the interviewer said how do you not know this basic thing and then he proceeded to describe a normal distribution 🤦‍♂️. Nobody told me that shit had another name.

It’s told during engineering🙈. I am not into data science or tech but I know that being into business side.

Here is what happened, the interviewer was professional and he asked questions I was not prepared for.20 mins in,my mind is scrambled

And then he asked me what 1*1 convolution is,I wasn't able to answer that(even though I knew the answer) I was completely blank.At this point if he asked about gradient descent ,I wouldn't have been able to answer it.

I was embarrassed, couldn't sleep for days.Because I was not able to answer 1*1 conv.

Lesson learnt: learn to handle pressure during interviews.

That is actually a good experience. It tells you how much pressure affects our performance.

I had a screening round with Google and they asked me what gradient descent was. I wrote a paper on it in my pg but was entirely blank during that question. Couldn't even remember a word.

Hi @Jackietrader I have 4.8 yrs of experience and working as an SRE. Started studying GEN AI and completed Google GEN AI L3 course. I am not able to find the direction to switch my role in AI and ML. I can spend 2 hr daily to learn new things and dedication towards it. It's just that I need direction. Can you please guide me where the job market is and how to prepare?

Not Data Science Interview but in the analytics part I had confused Central Limit Theorem and Law of Large numbers.

I was asked to explain Logistic Regression with math and intuition, I knew it but I bombed it due to the interview pressure. Pressure in certain amount is good but then most often than not it works against you like in my case.
