Apply online, got a phone call within a week. The first round is a phone interview about your background. Questions are quite standard, like what have you done in your graduate program, how does it help you to work as a quantitative analyst. Then second round is a 2 hours online test for 4 questions: mathematics, statistics, finance and programming. They're not very hard. The statistics question is actually an open question, it needs you to explain how you want to solve it, instead of just typing a number as the result. The third round is a phone interview with probabilities and brain teasers. I was not prepared very well for the probabilities. So the interviewer finished it earlier than expected. Could do better if I had some time to prepare for those interview questions.
