There is two phone round interviews and a superday, I didn't make it past 2nd round. The interviewers were very nice though and provided help if needed and helped walk through the questions a bit. It was 1 hour long.
online assessment and video call interview, asking probability and expected value type questions. pretty straightforward. The questions are quite difficult but interviewer is very kind and happy to work through questions with you

I did an interview in January. The interviewer was very nice and asked some probability questions. I answered the questions correctly but stumbled a bit. I didn't get a follow up interview.

The interview question was a probability problem, asking if 100 people are in the line and another line opens up, what should be my strategy. The follow up question was whether the answer was realistic and what would differ in the real world (and not assuing everyone makes decisions based on probability).
