Went through 3 rounds of interviews total, one phone and two in-person. Not too challenging just persistent. First was a one-on-one, then a two person phone interview followed by a 7 person group interview onsite with a tour afterwards. There weren't any obscure questions that I've been asked before, but nonetheless a 7 person group interview can be a little intimidating, especially when trying to make visual contact with each person while answering questions.
