I was emailed by a recruiter, and the process took 2 weeks. I interviewed with Apple (Cupertino, CA) in March 2022. Phone screen, two 1:1 video interviews with hiring manager and an engineer, live design challenge with two engineers. Didn't get to the final chat with the director. My resume was in the Apple job system, and a recruiter contacted me about a position I hadn't applied for. The screening and both 1:1 interviews went well enough to get to a joint vidcon where they presented a design challenge problem. The design challenge was a live series of questions over 1.5 hrs about design requirements and your solutions, unlike other design challenges that Apple usually presents to hardware engineers, where one is given half a day or up to one week to work on the complicated design problem at home, preparing a presentation that is given to the team. In this case, the series of questions involved details about a specific product that I hadn't encountered at work in eight years, so my rusty answers apparently weren't what they were expecting.
