I applied on line. The process took about two weeks. Then I got a call from HR. on site interview questions are very technical. with one brain teaser each round. There were three round on site interviews. I got rejected on the second round

Several days after I submit my resume, they contacted me to a on-campus interview. The interview was nothing weird and the questions should be pretty straight forward if you are major in finance or economics. Later, I was invited to the superday but then they told me that they were not going to hire sophomore. Anyway, the people interviewing me were pretty nice and there were not many brain teasers.

First round on campus interview with an associate and a VP. They started with resume based questions, like what's your favorite class. Later they threw me questions in probability and linear algebra after they found out I am a math major. A week later they flew me to the San Francisco office for a superday. That was 4 back to back interviews with two directors and two managing directors. Mostly technical questions.
