Pros
Amazon is the most innovative and fast paced company I have ever worked for. Amazon is changing the world and is continually pushing the boundaries of what is possible. Only the best are hired to work for Amazon, and the high caliber performance of colleagues is noticeable. Work Life balance is nothing like the horror stories of the NYT article, however it varies team to team. The South Lake Union campus is fantastic and makes for a great place to work. Dog friendly buildings and co-workers is a great stress reliever.
Cons
Amazon's culture and high expectations are not for everyone. Don't expect you hand to be held or shown what to do. Health and retirement benefits are good, but not exceptional. Much of this is compensated through signing bonuses and restricted stock units.
