This is what I encountered for my 3rd interview at Apple.

3rd interview would be with the Market Leader of South Asia, he would inform if it's the last interview.

you'd expect "tell me about your previous job roles and responsibility, who are you as an individual, why would you like to join retail?" for the role I interviewed for, the market leader given us a presentation task on an App, and what benefit the App could bring to the user.

Hope that helps. and remember to always put on a happy face.
