Had one interview down in their Seattle office. My interviewer was in the tax line of service, and he was extremely nice and conversational. It took about a half hour for the interview (I think those were the timeslots since they were recruiting from campuses and put all the interviews in the same day). He didn't ask too many questions. Spent a good 5-10 minutes talking about his own background and the program itself. He only asked two questions that were typical questions you could look up on Google even. We had a whole 10-15 minutes for me to just ask my own questions. Easy-going interview which helped calm the nerves a bit.
