Both of my interviewers were kind of stiff, neither was very conversational, which made me kind of nervous at the start. The buildings there are built into the hill, so it can be very difficult to figure out what floor you are on (sometimes you walk in to a building on the 9th floor). I managed to find my interviews without getting lost, but the directions were about half a page long, and a few people did get lost.
Overall, the interviews were a little stiff, but the school looks great. Great buildings, great city, and the students seemed happy.
