Passed my resume to a recruiter via LinkedIn and was contacted a few days later to schedule an Initial Screening with the Hiring Manager. I was then invited to the Amazon HQ for 6 in-person interviews about 2 weeks later. The interviews were about 45 minutes each and focused on Amazon's leadership principles. I was surprised by the number of behavior based questions there were, the interviewers would really dive deep to get the specifics of each answer you gave, but it didn't feel like an interrogation it was more like a conversation, which was nice! It was clear that everyone I met was incredibly smart and really looking for "Amazon" personality fit at this point. My best advice is to study Amazon's leadership principles along with your resume and be ready to go into great detail about how you showcased those same principles, be open to sharing your thought process and support anecdotes with quantifiable data as much as possible.
