The people who do well at Amazon are often those who thrive in an adversarial atmosphere with almost constant friction.
This matches my experience. People either harden up and become better or they get burned out and feel pushed out. It will be interesting to see what happens as time goes on, as Amazon reaches a point where their desire to grow as a company grows beyond the number of people on the earth who have the skills to work there. Eventually they are going to run out of people to employ who can help fulfill their big ambitions.
