First round consisted of two back to back 45 minute interviews on campus. One was strictly behavioral while the other consisted of a mix of behavioral and technical. General questions to understand your knowledge of IT systems, no coding or case interviews. Second round was an office interview where they fly you out and put you in a nice hotel, the typical consulting wine and dine. Office tour was pretty straightforward and concluded with two more short interviews, both behavioral with a couple technical questions. Found out about the offer about 2 weeks later.
