About what you'd expect when you sell your soul. You get a good price for it though. - Software Design Engineer Amazon Employee Review

Working conditions (small cubes), tools available (one-size-fits-all computers don't really fit all sizes), competence of project managers (disorganized, no formal requirements setting), the need to maintain your own systems (nighttime and weekend calls/pages), lack of testers, lack of support staff. Basically, engineers are highly skilled web developers and system administrators. The compensation scheme also doesn't put much emphasis on performance, so the compensation is pretty similar if you did a good job or a bad. And people who are jerks, who don't get along with anyone and disrupt teams, aren't handled. They stick around forever.
