Vantaggi
You're surrounded by bright, creative people, from diverse backgrounds. Truly a global company, focused on hiring the best candidates from around the world. All-hands meetings teach you about various areas of the business, and the CEO always shares bits of wisdom, followed by open, virtually anything goes, Q&A. Great stock benefits, if you can hold out through year 3. Open environment where constructive criticism is valued. You're typically empowered to run your own space.
Svantaggi
When Amazonians start to believe their own press, they can make bad decisions. Many strong referrals are rejected via bar-raiser arrogance, to the point that you no longer want to sponsor references for fear of a bad candidate experience. Too much time is spent finding the "bad" in good employees during annual rating exercises. Time would be better spent in making their great employees even stronger.
