Avantages
You'll work on bigger problems at a more massive scale than anywhere on earth. You will have lots of opportunities to expand your job scope and responsibility as you prove yourself.
Inconvénients
The company overall is run like a combination of Lord of the Flies and Atlas Shrugged. There are no centralized or standardized processes and everyone is trying to prove that they're valuable Promotions beyond L6 are nearly impossible at Amazon Corporate. Overall, the jobs at Amazon are severely under-leveled. Most people will leave an SVP job elsewhere to be a Director at Amazon, and when they leave a Director job at Amazon, they'll be an SVP elsewhere. This is by design. Everything is done as a panicked response, or worse, as a knee-jerk reaction to a Jeff B "?" email. It is rare to actually do something as a result of a long term strategy.
