Pros
There is a lot of work to get done and with frugality being at the core the value trickles down to the customer. Smart people and great opportunities to work on projects where you learn more on the job than any other organization. Demands of delivery are high and rewarded but politics are the new game you better learn to survive at Amazon. Now that we make money everybody wants to jump on the train and Amazon's doors are open to anybody who is willing to work hard even though people joining are joining to make the bucks not because they want to work for Amazon or believe in the customer.
Cons
Politics rule now at Amazon. Growth is great but not when you put people in positions they are not prepared for causing more damage than good. Bezo's has lost touch with what is going on in his own company. Truth tellers who care about the right thing are labeled as a problem just disappear while others watch and stay quiet so they can rest and vest collect the next stock vest and get out.
