Amazon

I had a wonderful time working inside an AWS team in Seattle. The team was very welcoming and gave me plenty of responsibility while also maintaining a lot of support. The main things that stand out about Amazon are the transparency of recruiting, performance review, and promotion, the shared ambition of the firm, and the early responsibility you get even as a college student.

Amazon can be stingy about certain things. For example, you have to pay for your own lunch.

Amazon also has high expectations for a software firm, as you are expected to significantly contribute in some way towards Amazon's goals of satisfying customers. But those hardly seem like problems to me.
