Apple Software Engineer interview questions

The interview process was what you'd expect from a company like this. I have about three phone screens (all of them were technical and the last one included a code snippet), followed by an all day on-site interview. The on-site consisted of one hour interviews every hour (11-5), and we're all very technical. I was asked to solve various problems (your typical algorithm and data structure subjects), as well as explain the various projects I worked on in my most recent position. The questions involved a lot of thinking, but I was able to find my way to the solutions after some time. All in all, I'd say it was too bad as I had prepared by practicing algorithms (searching, sorting, etc), and brushing up on some objective-c (I had to teach myself it in the two weeks leading up to the on-site). A good topcoder browse is a good resource for preparing to interview with this company.
