They ask you a lot of situational questions like how would handle if a coworker was stealing, but mainly once you get past the group interviews it's a lot about promoting the Apple brand.
I applied online. The process took 2 weeks. I interviewed at Apple (New York, NY) in May 2013
Interview
I completed the online application, then received a telephone interview. My interviewer was friendly, cheerful, and helpful, and rescheduled my interview when a conflict came up, with absolutely no hassle. I was asked to come in for an in-person interview, but I ended up not going in, as I had received another offer.

Question 1
The questions were generally standard, nothing was too difficult at this stage in the interview.
