The interview typically involves a phone interview plus the Loop (5 rounds) if the phone interview is successful. The majority of questions are on Leadership Principles unless it's a technical role. Unfortunately, so far I have been invited for three different roles. Amazon operates based on first come first serve meaning the faster you get through rounds of interviews more likely you get an offer. They don't invite a pool of candidates and shortlist them as they progress. My last interview was quite a painful one, I was invite for a phone interview with the hiring manager straight. After two weeks of preparation and stress as soon as I joined the call the hiring manager told me I had already filled out this role and didn't need me. I believe this is more of a poor individual behavior as my other interviews (more than 10 rounds) were quite respectful and mutual. However, the interview process of the company contributes to this poor behavior. I felt quite disrespected and extremely disappointed
