Had one on-campus in person interview, then a final round all-day interview at the Chicago office. The on-campus interview was scheduled a few days after the career fair and I submitted my resume online. I got an email the day after the interview inviting me for a final round at their Chicago office. That interview was a really great experience and I was offered the position two days later.

There are 3-4 interviews. There is a screening, a couple behavioral interviews, and a case. The case is relatively easy as the math is simple, it is just thinking about the situation.
