It was a bit grueling. They had us arrive in a group, then do a multi person (10+) interview 3 times. We were lead into a room where I sat at a table with about 6-10 people who peppered me with questions. That lasted about 15-25 minutes and then did the same in the next room and the next room. They were all courteous, and it was very professional, but I bit inconsiderate to the interviewee to be expected to perform like that. Especially because very few actually reviewed my resume before they asked questions, so some of the questions were a waste of time. Also they did a few really cliche interview questions.
