There will be 4-5 rounds in general. The first round is a 30-45 mins round with the HR. The second round is data science-related rapid-fire questions and then a case interview relating to time series data science questions. Third round is a data challenge (take home). The fourth round is explaining your solution to a panel and the fifth round is meeting with the executives.

General data science questions with a heavy focus on time series.
Typical HR interview to start off with. Then an hour long technical interview. The technical interview was rather strange, lots of writing down easily google-able formulas and less about actually understanding and talking about actual ML concepts. It was more like a rapid fire questionnaire of ML than any assessment of real comprehension/ability.

The first round of the interview was given by HR, I was asked to describe and explain the work experience with less technical terms. The second round was with a current data scientist: I was given several cases and asked to give solutions to those.
