I applied online. The process took 10 months. I interviewed at Amazon (Charlotte, NC) in Mar 2016
Interview
Online video recorded interview in lieu of phone interview. Most of the questions (aside from the math flow) were about challenges, setbacks, or failure rather than achievements. The math question was identical to one i had practiced on glass door.com. I used a MacBook Pro and had no problems with the interview process itself.
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.
