Submitted application through university website. Got three phone interviews for different departments. I was then flown out for day of interviews about three weeks later.. Was scheduled to have 10 that day. Questions ranged from knowledge of the design process, brain teasers based on averages and displacement and basic physics.
I applied through college or university. I interviewed at Apple
Interview
Phone interview-40 minutes. All the questions are about the details of my resume. The hire manager also asked some basic mechanical questions for example how to design a gear. If you change the speed of the gears will the power transmitted to the next gear change. At first I don't answer some of the questions but the hire manager inspired me a lot.
got referred by current employee, got an email setting up interview extremely fast. Had one 45 minute interview with someone who works in the group I applied for
