I interviewed with the photography manager, then the entire photography team (six people) in a room. The entire process took about an hour. The interview didn't seem to have a set agenda of questions, and seemed more like a "get-to-know-you" style interview. I had already worked there as a temp before and knew several of the interviewers on a personal basis. The most important thing is to seem laid back, yet hard working, because that's the vibe of the company.
