Brought in with a group of ~15 interview candidates, took a typing test on the computer first, interviewed each candidate individually with 2 interviewers. We all sat along the wall waiting for our names to be called up. They had about 5 groups of interviewers, although you only interviewed with one group.

They call about 20 people that want the same job and you interview for approximately 30 mins with people in a "room" made out of dividers. There are about 6 "rooms" in a large meeting space.
