Began with a quick phone-screen (15-20), mostly to set up the first round interview. First round was split behavioral/case. Case interview was done in Webex, so download it ahead of time and make sure it works. Interviewer shows you slides but you do the explaining over the phone. When they say it "works best" in IE, that means it *only works* in Internet Explorer. Not sure how it would work for Macs. Case was pretty straightforward, some math; interviewer would point to where my numbers didn't match up and let me rework it. Think he was mostly looking to see that my thought process was in the right direction. Final round in the office a few days later, consisting of 1 written case, 1 regular case (market sizing question), 1 behavioral, 1 demo/presentation, and lunch. With the written case, they give you data charts with a couple questions to answer, leave you to work it out, then come back 30-40min later to go over the answers and ask you more questions. Interviewer was really nice and helped point me in the right direction when I was stuck. The demo was a brief overview of the work they do, but before explaining key parts, the presenter (interviewer?) first asked me "how would you go about doing this". Again, seemed like he wanted to see if we were thinking on the same wavelength. Everyone was really nice, more concerned about if you're smart and can think about things than specific skills. Overall it was a pleasant experience.
