2 phone screens followed by 5 interviews. All 5 interviews were mostly statistics and probability based. Some basic coding questions were asked as well. Maybe some basic finance knowledge would have been helpful. Overall quite challenging
Interview questions [1]
Question 1
A lot of statistics and probability puzzles, minimal coding.
Got asked very easy questions which I solved almost instantly. Had a good chat with the interviewer because there was quite some time left. Was rejected two weeks later on a Sunday. No feedback at all.

Was phone screen + 1 hour online screen a few days later.
