I had two rounds of interviews. The first round I was interviewed by the Director of my team and a Data Scientist, the second round I was interviewed by a Lead Machine Learning Engineer who was more techie. First round was some general questions about past experience plus a bit of technical questions. Second round starts with a take home assignment, followed by a full blown technical interview.

Questions asked are mainly based on Sql - easy to Hard level questions Cloud - basic questions only Ml - basic to medium level questions Although it was not tough and interviewer was also very good

It was 30 min introductory 1st stage interview (within this interviewer had to check his door twice). He asked explain my past projects which I explained. However he kept saying that we are only going to do customer churn nothing extra. My cv should have most of information about my 4 years of experience and phd level studies. If you want to do only customer churn then why interview a person who has research based experience. When I asked question, are thinking of using NLP techniques around customer reviews ? He said NO. It felt like waste of time.
