Lead Data Scientist Interview Questions

409 lead data scientist interview questions shared by candidates

The questions were very general, such as “Tell me about a project you worked on.” There was no context provided, no discussion of specific technologies, and no effort to connect the questions to the role or domain. Additionally, they mentioned they couldn’t share any details about their own project due to an NDA, which I was never asked to sign. This made it difficult to have a meaningful or relevant technical conversation.

I won't divulge the custom questions they had because of an NDA. But I will divulge the interview questions that are carbon copy menial tasks. Of the first three phone/live-coding interviews, I was asked to do a merge sort. I guess I understand that they want to make sure I can code. But there's got to be a better problem. The many in-person interviews were (1) 1.5 hour coding-by-myself on a laptop, (2) describe a problem you worked on in detail, (3) "NLP" interview that didn't focus on NLP, instead they focused on AB testing (which is fine), (4) Lunch interview, (5) culture fit interview, (6) follow up/close/discussion interview. To be honest, I don't remember much near the end. I think I went directly home after and slept for 12 hours.
