I've interviewed with Amazon before so I knew what to expect. They are very very thorough and really drill down following a rigorous script. Have 'use of data' examples for everything. Sadly in this case they were let down by HR. I was at the end of my first competency example when the interviewer said "was that part of an internship?" I replied that it was my latest job of 2.5 years. He had my old CV from 3 years ago despite me sending it in twice. Hence he had no access to my latest CV. I followed up with HR and provided my CV again and was reassured it was now on the system. When I went onto the online application system myself I found the old CV still there. - Worth checking. My advice to anyone applying to Amazon is to ask for specific examples from your interviewer on teamwork culture and don't let them off the hook with generalities like "oh we have great team culture here, we go out for drinks now and again". 14 leadership principles alone breed a culture of individuals and they don't mean anything without a team - which leadership implies. 7 Amazon interviewers in a row have failed this question when I have pushed below the surface for an answer.
