Amazon literally lists out the leadership qualities they look for and asks people to prepare for them. You prepare for them, tell the story, and they don't bother with follow-up questions most of the time.

I find behavioral questions to be bs anyway, since how someone presents themselves during an interview and their day to day behavior can be very different. Atleast here, you do your preparation, spit out your story, and you're done. Slightly less bs way to interview for personality qualities.
