Apple Wireless Systems Engineer interview questions

Internship position. Applied through a school career center. Was contacted by a recruiter at Apple, who was very polite and professional. I went in for the interview in person and my interviewer was not too prepared for the interview, he didn't even have a room ready. No problem though, we found a room in a jiffy, and proceeded with the interview. The engineer was pretty exhausted from a recent trip overseas, but still conducted the interview.
