Pluspunten
I'm working at AWS. The system is well made but also it's complicated enough to let you spend your time only to learn it for a year long.
Minpunten
It's a sort of survival game here. Also it seems the company doesn't care about employee's departure. There's always many people on the line willing to join the team but once they join the team sooner or later many look for another opportunity. Management layer is filled with non-engineering people who mostly care about numbers. You should expect working more harder here even weekend. Engineers are responsible to everything that includes operations, deployment and on-call support. Which is fine but I don't feel it's that much cooperative environment. Visibility management is a must here.
