Apple Software Engineer interview questions

2 interviews, each interview is 2 hours with each hour being done with a different interviewer. I didn't feel a difference i terms of difficulty between the 2 interviews. I feel like there were lots of questions so lots of topics were covered in the interview relatively to an interview with Nvidia for example.

Interviewed with the whole team. Everyone was easy to talk to. Mostly interested in my background. The coding challenges were relatively hard but doable, the interviewers were collaborative during the white boarding.
