Apple Hardware Engineer interview questions

Got contacted 2+ months after submitting CV. 1st phone interview was with a senior hardware engineer who asked a lot of questions about the projects in CV. All questions are technical. 2nd phone interview was with the group manager. It was all about the position. Only several technical questions. Not hard. Both interviewers are really nice.

The process took 5 weeks from recruiter contact to decision. First a phone interview with the hiring manager and then was invited to Cupertino for onsite interview. All went quite positive and a week after the onsite a manager I interview requested for an additional round where he asked questions no quite related to the position.
