My first interview was with the recruiter. They asked 4-5 technical questions. Two out of five were topics you simply wouldn't commit to memory. Had I not had a computer next to me, asking them to repeat the questions, I would not have gotten through them.

My second interview was with the hiring manager. We shared a common background in virtualization. We poured over it, spoke about our passions, the history, and how it was today. He wanted to know why Apple and did not ask many technical questions.

I was then flown out to Cupertino. This was a 360. I interviewed with just about the entire team, six people, and covered questions from storage, networking, application, and scripting (whiteboard) – just about any area I had touched on.
