two technical interviews + 1-panel technical interview with 4 interviewers. All algorithm + math problems. They prefer to ask DP problems and probability and stats math problems. It is overall not easy.

the discussed topics themselves are very broad and include anything from your past research to open-ended questions on stats/dl/games; I had 6 rounds but usually folks have 5 to 7 of them, depends on the number of teams that are interested in u; all interviews were recommended to be finished in 40 minutes, but we managed to chat with interviewers for 10-20 minutes after the technicals; the staff was kind and the process itself more resembled some type of informal and pretty chill chat
