Several rounds of very standard quant interviews. Some brainteasers and some probability problems, which can be solved easily if you have practiced enough. There is also a round of programming interview. It was implementation heavy, which requires you to think quickly and have good program practice.

A 45-minutes interview related to coding in Python. The interviewer is nice and is from the same university as mine. He is also knowledgeable and I have learned a lot from him.
