I applied through a recruiter. The process took 3 months. I interviewed at Amazon (San Diego, CA) in Sep 2016
Interview
It was very casual. I was emailed to set up an interview about 2 weeks before the interview date. I was flown out to San Diego and they put me up in a nice hotel. The interview itself was 2 x 1 on 1 interviews with basic STAR questions (name a time you improved a process, etc.) and questions where they wanted to know what you would do in a given situation. The whole interview took less than 2 hours.
Star Method and Leadership Principles. Just study these from the materials they give you, and form a story for each principle, and when they ask questions, you can see which principle they are asking about.
Interview questions [1]
Question 1
Tell me about a time you faced a conflict or disagreement at work and how did you handle it?"
Multiple online tests after application, followed by a virtual interview with various staff. Staff did not want to be on camera and did not have many good things to say about working there.
Prior to even speaking to anyone about a possible interview there was a long and lengthy testing required. Really disappointing to finish with no feedback or additional details. I only received an email post test.
