Apple Product Design Engineer interview questions

Expect 5 to 10 rounds of 1 on 1 interviews asking questions of different expects of your experience, case studies and technical knowledge. Best to prepare and schedule ahead. Some reading of mechanical engineer basics is recommended e.g. beams. The most difficult part for me is the design challenge review presentation.

Got an email to do design challenge. Had 24 hours to complete it. Sent it back early but they came back with more questions. i responded to the questions but they told me the job criteria changed so didn't get the job.
