What I'm hearing from others is this... there are good teams at amazon... amazon is huge but the overall culture is not what you describe. I guess I'm looking for a more overall picture rather then someone viewing it from the perspective of a good team.
>They absolutely can push back and say that no-one in their team deserves to get PIP'ed
