How Amazon interviews
Amazon runs hiring in four stages it publishes on its interviewing page: an online application, a role-specific online assessment, a phone screen, and an in-person or virtual "interview loop." The loop is built around Amazon's 16 Leadership Principles – candidates typically meet four or five interviewers, each assigned a principle to probe with behavioural questions, and one is an independent "Bar Raiser" from outside the hiring team who holds a veto on the decision.
Because each interviewer scores against a named principle, preparation is less about the role's technical surface than about having concrete past examples ready for every principle – several worked stories rather than one, since any single interviewer, the Bar Raiser included, can sink an otherwise strong loop.
