Entrevista
I sent my CV and cover letter directly to HR. Then I got short listed. HR sent me email to arrange a phone interview with me. There will be 3-4 rounds of interviews before the final interview. The problems will be more and more difficult. If you can't answer every question correctly, you will be very likely to get rejected. All my questions are brain teasers. But I have friends who only received mind math + probability questions.

It is noon. The hour hand and minute hand overlap. When is the next time these two hands overlap again?
There are 3 coins. One coin has heads on both sides, one coin has tails on both sides, the third one has head on one side and tail on the other side. Now I pick up one coin and toss. I get head. What is the chance that the coin I picked has heads on both sides?
There are 25 horses. Each time you can race 5 horses together. Now you need to pick the top three horses among them. How many races do you need to conduct?
Several phone calls to go to the final round. The phone calls consists of mathematical, probabilistic brain teasers which was not that hard for a mathematics major. Final round was to harsh for me, strong mentality is required

Lots of expectation/probability questions. Make sure to study game-theory type question that involves expectations. Specific concepts in stochastic processes don't seem that important. The first two were relatively easy. Just make sure to ask a question if there is any uncertainty
very fun a lot of interesting problems. The person which was managing the interview process was easily aproachable and really nice to talk to. Also interviewers seemed really interested in the problems given and gave me a lot of chances to talk about them
