Apple NPI Ops Program Manager interview questions

Obtained an interview through alumni referral. I had HR a phone screening interview with an HR manager. The conversation was basically testing your fit and energy level. And then the hiring manager did a phone interview. This was more detailed discussion about your experience. I was immediately notified about an onsite interview. The onsite was packed with 7 interviews back to back. It was the usual - why apple, why are you a good fit, technical skills etc.
