Apple Hardware Engineer interview questions

I had 1 phone interview. We mostly talked about my research.

Submitted resume online and got an email from recruiter for an on campus interview. Its about 45 mins long. Asked about your background and projects. Couple technical question regarding computer architecture and digital circuit. The guy was really cool and laid back. He asked if I had experience with verification tools/software and why I want to work for Apple. He was really passionate about his job and was very knowledgeable.
