Nothing like normal retail. Everyone by now knows about the BIG group interview/hiring events Apple does. It's after that you need to focus on. Essentially just be yourself, like having a conversation with an old classmate and you're catching up.

First interview was at the same time as 70+ other people in a group interview. Leads to more 1:1 interviews. Number of interviews you go through may vary. Out of the initial group only 2 people were offered jobs. I was one of them after 2 additional interviews. Other person after additional 6 interviews and was offered 2 months later.
