Round 1: Phone interview with recruiter. Recruiter asked some general questions about my background and details to set up round 2. Round 2. Interview with Technical Manager. Was asked additional questions about my background and answered my questions about Apple Round 3: Design Challenge: A design prompt was given with a specific problem but very general requirements (presumably to gauge your approach and creativity). I created CAD models, FEA, and engineering analyses in a presentation that I sent them Round 4: On site: I was interviewed by the Senior Recruiter, three PDEs, a manager, a director, two senior designers, and the technical manager from round 2. During lunch, I had to present my design challenge which was dissected in detail. Interview questions ranged from my background to previous projects to engineering questions to test general engineering knowledge. All in all, it was a very thorough.

i had my interview today and was asked the same question. also similarly, the interviewer had no sense of humor. it was not a enjoyable experience because i think i gave like 3-4 different ways of making a cantilever, but i was asked "what else?" like 10 times for the cantilever problem alone. i also have 7 years of work experience, but there was 0 question asked about it.
