Interview process was easy and process oriented. Based on my research, I was under the impression that 75% of the questions will be on Leadership Principles, however first 20 mins turned out to be just ONLY technical (architect's level). Amazon is not for experienced professionals who are at the mid-manager level. Either you directly apply for most senior level position or as a college graduate. Definitely not for seasoned professionals like me as technical acumen greatly differs for every PM. 1 hour initial phone interview is extremely less time to learn about a candidate's background. Interviewers mindset are psychologically expecting answers based on Amazon's project execution point of view and business objectives. Technical PMs are not to be judged based on their current project handled, such as legacy application migration. Every project has its own complexity.
