Amazon interview FAQ
How important are the Leadership Principles at Amazon?
They are the single biggest factor. Roughly half the loop is behavioral, and every answer is mapped to specific Leadership Principles. Strong technical skills with weak LP stories frequently get a No Hire.
What is a Bar Raiser?
A trained interviewer from outside the hiring team with veto power, there to keep the hiring bar high. They typically run the hardest behavioral round.
