Pros
Good salary and talented colleagues.
Kontras
Poor work-life balance: unless you set and stick to very clear boundaries the company will take and take and take until you reach burn-out. Very high stress levels and combative management - expect to be shouted at and disrespected. Super-ambitious targets which can only be achieved by burning out employees - this is why most people stay less than two years (Amazon has a very high churn rate). Basically the New York Times article on Amazon was pretty accurate about white-collar work within Amazon (I don't know about the blue-collar work). I've not spotted anyone crying at their desk or in the toilets, but plenty of people just leave for a workplace that values its employees more. Amazon is congenitally tight-fisted on everything except salary: this is the corporate principle of 'frugality'. Amazon genuinely does put its customers first, at the expense of employees. Whether this is a good thing or not for investors in the long-term, I don't know - it seems to be working well for them so far. Staff generally don't feel valued - the relationship between company and staff is "we'll pay you well but work you until you drop".
