Apple Systems Engineer interview questions

I was contacted by a recruiter at Apple for the systems team and he talked to me about the role, requirements, my background and sent me a questionnaire about some logistical items. Next, a call was setup with an engineer on the team for 30 mins. He asked some questions and then gave me a review on the how I performed in the interview.

The interview included multiple one on ones with 6 people including hiring manager and recruiter. We worked through example modeling / analysis problems on a white-board and I gave a presentation over lunch.
