Amazon

The interview was nice. All the people I interacted with there were professional and polite. My colleagues were all competent coders.

There is no documentation, and Google searches won't help since they have all their own tools. Your only solution is to read code and constantly ask other people.

You will get negative feedback no matter how well you do; they constantly push you to do more. Resist this. Read code and understand things; it is the best way to succeed there.

Half of my team was gone from Amazon within a year after I left, including the manager that was pushing me to do more and more. I never got a sense that people liked working there.

The only reason I found to work at Amazon as a software developer is to work hard for 3 years, have no life outside of it, get your benefits and bonuses, and then get out.
