Exceptional Environment for Learning & Innovation
Pros
The interview process is rigorous but provides an excellent foundation for what you need to know Day 1 -- that the leadership principles are REAL and there is an expectation that everyone remain laser-focused on these ideals. In every meeting -- internal and external -- you will hear people talk about things like customer obsession, bias for action and invent and simply. So, there is a method to the madness as the Amazon culture is truly unique.
Cons
You need to be self-driven and motivated to learn to be successful at AWS. It's key that you take the Learn & Be Curious principle to heart. I find that my onboarding buddies are helpful, but their approach is truly hands-off. If you're new hire you must lean in and ask for what you need. There is no hand-holding.
