Apple NPI Operations Program Manager interview questions

I first had a phone interview with the recruiter which then lead to another phone interview with a hiring manager. After that, I was invited for an on-site interview with 7 different people. Each interview took about 30 minutes. They had to switch the interview schedule around on a few occasions since some of the people interviewing me were pulled into other meetings.

My resume was passed on to a hiring manager through referral, the hiring manager called me to set up 30 min telephonic interview. THe interview went very well and asked the recruiter to schedule me in for a f2f with a larger group of people. The recruiter called me and discussed my background for 10 mins and set me up with hiring coordinator to schedule my interviews and travel. Finally, my interview was scheduled with 6 interviewers 30 min each back to back. It was very stressful to do interviews for straight 3 hrs back to back.
