Apple Engineer interview questions

The interview process was fairly rigorous. It began with a 30 minute phone screen where I was asked about my experience in the field and my interests, and I was presented with a slightly more technical physics problem. I was then contacted about having an onsite interview the following week. The onsite interview lasted for almost 7 hours, and consisted of 10+ interviews with employees in the division, who asked about everything from specific design questions to why I wanted to work there to what I valued in a job. I also presented my numerous projects. The following week, I ended the process with a shorter interview with two upper level managers. To the best of my knowledge, everything went very smoothly. Unfortunately, I wasn't offered the position, which was obviously disappointing after 10+ hours of interviewing.

Phone interview with HR rep that briefly touched on my experience at previous employment. Then a technical phone interview (about 45min). Asked all sorts of questions from microprocessors to voltage regulators. Very specific knowledge necessary. He definitely knew his stuff. Come prepared!
