Vantaggi
Salary. They pay you piles and piles of money and stock, although a good portion of the money is in the form of a bonus that you owe back (prorated) if you leave _for any reason_ during the first year, and a similar scheme for year two.
Svantaggi
This is a place that has no respect for it's employees or any life they may have outside of work. Within 2 weeks of starting, I was informed by my manager that I the other members of the team all worked nights and weekends, and that the same was expected of me. Things went downhill from there, until I was working 80-90 hours each week and burnt out on anything else. Amazon fires a good percentage of its workforce each year, and only gives raises to the top 20%, which produces a culture of extreme fear and competition, with team members sabotaging each other, and plenty of inter- and intra-team politics.
