Got a cold call from an internal apple recruiter on linkedin. She spoke to me on the phone about touch panel hardware engineering opportunities, and said that the first step in the interview process was a skills test. They give you 24 hours to finish, and it consists of some open ended, and some fundamental electrical engineering questions. After taking the exam, I have a sneaking suspicion that the presentation is every bit as important as the content. I say this because I hand wrote my answers and scanned them in; I happen to know that I got 6/7 correct, however I just didn't polish it up. Well, ok, I did one powerpoint slide for the final question. Best of luck friends.
