Amazon Principal Technical Program Manager interview questions

Recruiter sent a set of questions to answer and send them a copy. Questions were focusing in your failures, achievements, Amazon leadership and how it maps to your experience, as well as explain the most difficult project you got involved. I needed to prepare that before they arrange/offer a phone interview. Prior to my interview, I expressed the recruiter that I do not write code and I do not want questions to be asked in coding or SW design. I did not have any problems with SW project management, requirements and etc. My main background was HW. In my phone interview, there was not any single question about Amazon leadership or any questions about my resume. Only question was about API design and detail system SW design. I thought this is program management position and I felt uncomfortable with SW API design questions.
