Apple Hardware Engineer interview questions

Apple is a large company with multiple technical teams that have their own interview process. Generally 3 rounds with phone screen, basic technical/behavioral then a panel interview. Recruiters for different teams don't talk to each other or help you find better fitting roles, and that's a red flag indicating how siloed, secretive and noncommunicative the teams are within Apple. Never heard from anyone after submitting resume for other roles after one interview didn't work out mutually.
