Applied through career services at the university. Initial round was a pretty straightforward case, no big surprises or anything. I did ask a question in the beginning that the interviewer knew I needed to know to solve the case but he said "we don't have that information at this time" and then proceeded to tell me later "Oh you asked about this earlier, here is the answer now". So try to be really structured and don't ask for things in a random order. You look confused and if you get the right answer, lucky as well.
