Pros
usually you can get hired at close to market rate and not paying out of pocket for healthcare benefits is nice. the benefits package really is not bad at all.
Cons
expect: - to be assigned responsibilities far outside the realm of your expertise (or pay) - long hours on call - a culture that is very finger pointy, due to the company's tendency to go for mass layoffs whenever they encounter the slightest business problem - "flexible time off" system where time off is never actually approved and probably borderline illegal - will likely never advance further than what you're hired for because they prefer to hire outside for senior/executive positions and the people that do move up tend to do so from very blatant nepotism - completely dysfunctional technical culture, where most of your job will not actually be engineering, but rather chasing down and doing a detective mystery on who is responsible for or who owns the thing you've been tasked to fix - completely irrelevant "performance" system that isn't transparent at all - could go on but you get the idea. avoid.
