They asked me tons of probability questions and programming questions. This was an operations/support role and the team lead is a fresher (although, he's a PhD) with no industry experience so doesn't really know what to look out for and how to interview for a support role. Also, they call you in to the office, interview and drain you out for over 6 hours. So if you're going to their office, be prepared for that.

I have an all-day onsite interview for 9 rounds, 8 hours. The interview process is good, people over there are all smart and nice person, the office is good too. The HR is very kind, but they took a long time to make the final decision, about two weeks after the onsite interview.
