Amazon Sr. Project Manager interview questions

I was contacted by an Amazon recruiter via LinkedIn. We had a brief conversation about my career background. He then matched my profile with few teams that were looking to hire. I was approached by an interested hiring manager and his peer each was an hour long conversation following the Adler method of one question drill down interviewing. I was asked to take a test and give a 4-6 page write up on an innovation I am proud of. Later I was invited for an onsite interview in Seattle which was with 6 individuals focused on the Amazon Leadership principles and my previous experiences that will align those those principles. The interview method was again Adler type - One initiative but drill deep with 15-20 questions on it.
