Apple Product Design Engineer interview questions

I actually did interviews for 3 separate teams, and had a good experience with 2. I did 2 technical interviews each and then a full day interview with six 45-minute interviews with different engineers, some technical and a behavioral. It ended with a design challenge.

1 call with HR, 1 call with hiring manager, 1 design challenge, then 6 round interview with team and presented Design challenge. Each round was 30 minutes sometimes with one or two people.
