Amazon reviews

Ridiculously hard to get promoted. You're more likely to see incompetent managers get hired into positions that they don't want to promote you to. Performance reviews and compensation systems are set up to allow the company to work you harder and pay you as little as they can get away with. Basically, you will only get a promotion or a decent raise when you work so hard that management runs out of excuses not to reward you properly. Very top-down management style. Every engineer's goals are the result of his or her manager's business goals which are trickled down from the "S-team" - the top level VPs of the company, and so bottom and mid-level creative initiatives tend not to happen. Engineers have to deliver on project after project with overly aggressive deadlines, support a huge operational load (i.e. pagers going off in evenings and weekends), and are then held accountable for quality-related issues. Many teams with bloated mid-level managers who demand lots of meetings, book keeping, reporting etc. TPMs and Dev Managers have to depend on tribal knowledge and personal networking to get anything done. Company emphasizes "Leadership Principles" which are the basis for how everyone ought to behave, but is vague and contradictory and only gives the impression - to those who drink the Kool-aid - that the company appreciates hard work as well as results, but in reality, they're no different from any other company who stack ranks their employees based on all sorts of subjective opinions. Reviews are full of BS and are mostly written after ratings have been determined. Eventually, the only engineers with rewarding careers at Amazon tend to be the fortunate ones whose managers know how to game the system, rather than play along with it. Everybody else eventually leaves - burned out and under-appreciated.
