You will have one interview with HR who will then also help you prepare for your additional interviews. You will have a phone screen with the hiring manager and then a formal "loop" with ~5 people. One will be the bar raiser and while all 5 people do not need to be inclined to hire you the bar raiser can block a hire if they are not inclined.
Interview questions [1]
Question 1
All questions will be either a case study or based on their leadership principals.
Two phone screens followed by a loop of four individuals plus a bar raiser. Questions are based on leadership principles and are looking for examples from work history. STAR format is encouraged and your answers should be clear about what you did, what the problem was, what your results were and what you learned.
I applied through an employee referral. I interviewed at Amazon
Interview
Amazon’s interview process is very rigorous. Plan to spend hours preparing and interviewing. Focus on their leadership principals and go deep in your response. Expect to spend 45 minutes with 4-5 people each will ask at most 5 questions. One person (who likely isn’t a direct link to the role you are interviewing for) is your bar raiser. This and the hiring manager are the two most critical interviews.

Question 1
Ensure you have answers around being customer obsessed and good with data. These are table stakes.
