Apple Technical Expert interview questions

First interview was a FaceTime interview- very casual, chatted about my CV and the role. Then got an invite to their hiring event a week later. Second interview was a panel/group interview that was like speed dating - I was interviewed by 3 groups of 2 Apple store managers and spent 20 mins with each. I enjoyed this as it went very quickly and it was good to chat to different managers. Typical questions asked- why Apple? Tell us about a difficult customer...etc and I was invited to a third interview the next day. Third interview was with two different Apple store managers- same format, few questions about my cv and how I would adapt to this role. Was called a few hours later with a job offer.
