None. They hire through a temp agency (Adecco). You basically have to keep up with the daily quotas and you will be fine. Nice atmosphere and they have free coffee!
One interview with 3 managers. Asked about my bacground and past jobs. They asked for my resume, availability and experience. This wad through an enployment agency, so I already knew about the compensation and didn't really have any questions.
