Amazon Senior Program Manager interview questions

The process took over three months. I submitted my application through a referral in the team. The hiring manager forwarded my application to the recruiter. Post the initial recruiter call, it took over a month to schedule the next phone round with the hiring manager. (In the process the hiring manager had changed). I was invited onsite for 6 rounds of interviews and also was given a written interview question to attempt and submit prior to the final round of interviews. Got a positive response two weeks after interview date.
