Question 1
They asked me about hackathons and Math Olympiads I have written
Standard interview for them, a call with some probability questions. If you get three questions right you pass, otherwise just hope for the best. Onsite is where it gets interesting but didn't make to there
Application by web form, received an online test later, then I had the first round interview online, doing some brain teasers questions, which msy be quite different from those you found in green book, more complicated and practical. The interviewer is smart but quite arrogant.
