Amazon sr Technical Program Manager interview questions

My interview with the recruiter was rescheduled twice with the first time about 30 minutes before the call and the second time after me waiting on the call for 20 minutes. When we finally connected on the 3rd attempt, I was told I needed to be a architect to lead technical architecture design, which is totally not mentioned in the job description and it doesn't make sense for a Program Manager to lead and make architectural decisions. I hope this recuiter knows what she is doing. Of course my interview ended with this recruiter.

The interview has 5 rounds with more focus on system design. Each interviewer focuses on specific Amazon principles. Please check for Amazon principles and prepare your answers/scenarios from past experiences.
