First round 1:1 on campus at target school. Surprisingly no technical questions - all fit. Other candidates at super day said they got technical questions first round. Super day consisted of your typical math/probability questions.

Started out with one round of campus interviews. The interviewer was relaxed and gave simple mental math problems and expected value games. For the final round, was flown out to Chicago, put through tour, a group exercise, and four 2 on 1 interviews the next day with brain teasers after brain teasers. The firm certainly invests a lot in making a good impression on all interviewees. Over the top accommodations and experience in the office.
