There were 3 rounds = 2 Technical + 1 HR. Process took 2 days. Both the technical rounds were scheduled on the same day. One with Data Science Manager and other with Data Science VP. First round was schedules for half an hour but it got extended till 1 hour. Second round got completed within half an hour. In the first round the questions related to your previous work, ML algorithms, SQL and python coding were asked. Also they asked the scenario based questions. In the second round, small case study was given which was quite easy.

It was a day long process. they have directly called me for the face to face. First round was written based on probability, statistics and data science. no domain specific questions, after that HR said to wait for a week for results, haven't even asked for water. worse interview experience in a while.
