Interview
Two phone interviews, probability questions, pretty tricky. Interviewers were both very nice/humble, gave helpful hints along the way.

Phone interviews (at least 3) - questions were of mixed difficulty (some pretty hard) but the interviewers were friendly and they gave helpful hints. Kind of fun - review probability and game-type questions.
