Apple Product Design Engineer Intern interview questions

Still in progress First interview was about 45 minutes long via WebEx Straight into technical questions without any behavioral questions Questions were such as: How to connect gear to shaft in multiple different ways Cantilever beam question asking areas of maximum stress and the type of stress Does the shape of the beam affect stress If you were to design a battery spring what are the main parameters that you would consider?

The first round was from on campus college recruitment. I was given 2 minutes to talk to the recruiter and was asked to come back later for a 30 minute interview. The recruiter didn't get back to me for over a month, and then told me they wanted a second interview. I did an hour long phone interview with the manager. I received an offer after the second interview.
