OA is 5-7 questions of math covering probability, statistics, linear algebra, calculus, and game theory in 45 minutes. Should be good with enough preparation. Just a regular online assessment most companies give.

The interviewers were very nice people. The process is relatively short. It’s composed of 1 HR screening, 1 technical interview, and then it’s the super day. The interviewers were very thoughtful and helpful throughout process and were happy to give feedbacks.
