Tell me about the machine learning project you recently done.
7 rounds, consisting of three technical interviews and three HM interviews, one MD interview. The recruiting is depending on the team's interest. Got rejected by the MD due to the mismatch in the experience. I guess they favor people from statistics or CS backaground.
