I applied for a job during a hiring event last October. Went to the Michigan Ave. store in Chicago and was interviewed with other prospective employees. Managers from all the Apple stores in the area were there and I had a fun time even though I didn't get the job.
If you're going to apply for a job at Apple, be sure to remain calm. We were asked amusing questions such as what the most embarassing song on your iPod is, why you wanted to work here, and what brought you to the Apple community in the first place.
Near the end of the group interview, we were asked to get in groups of 2-3 and present Leopard to the managers. I thought my group did a nice job, but I was probably put as the weakest link. My performance was great, I guess it was the fact that I wasn't wearing a three piece suit that was the death knell for me. I was so underdressed compared to others...
