I was initially contacted by a recruiter from Apple. He then set up phone screenings with three different teams.

They then flew me to a recruitment gig they were having in Europe. I had four interviews where I had to explain how things worked and do some coding exercises on the whiteboard.

Around two days later, I was told that I had good skills, but there was another candidate who looked like a better match, so they decided to fly him over to California for the on-site interviews.

Overall, it wasn't a very hard interview, and I thought I managed to do well. The people seemed rather friendly.
