Apple Software Developer interview questions

1 phone interview with a team manager about my past experience (discussion on resume) and the expected intern role. The manager primarily wanted to see if I'm interested in the role and etc. After the phone interview, I was invited to an onsite interview to meet the recruiter and one of the lead engineers from the team. The onsite interview was all technical questions.

Initial screening by the hiring manager and two other employees. Hiring manager and the first interviewer asked open-ended questions with emphasis on the previous experience. The third interview came after the screening C++ example (see below). The questions become more technical, but the interviewer was friendly and helpful. Based on the first impressions, the group I was interviewing for seems to provide a friendly and productive environment.
