There were three rounds. First one was an introductory call with the recruiter. Second round was about 45 minute call with the Team Manager and a senior member of the team. Interview has some basic questions about sheet metal forming and tooling. Third round was an intensive round. It lasted about 5 hours and I met different people at Apple who would be interacting with a person in the tooling engineer role. There were a lot of questions checking the candidate's knowledge about sheet metal forming, GD&T and manufacturing process and lean manufacturing.

Standard phone interview, then two on site interviews. Some people were late or did not show. This caused rescheduling. A long list of written questions and several projects were asked for which was really too much for an interview.
