Applied through career center. First round interview was on campus. Fairly straight forward, brief intro of the interviewer and then yourself. Dive into the case study pretty quickly. More laid back than consulting firm case studies. Second round was a super day at their headquarters. 2 case studies and 1 behavioral interview in the morning, and then asked back for another case study in the afternoon (not all candidates were asked to stay). The cases were fairly similar to the first round, although slightly longer and more challenging. Behavioral interview was pretty standard. Nothing too tricky.
