Pros
Potential to advance quickly up the ladder (because of high turn over rate). Lots of opportunities to learn across many different fields (because you'll have to do every job there in some capacity). Small community (if that's your thing).
Cons
Work/Life balance is really poor, between pager and various "crises" you will spend at least 60 hours a week working. Management does not seem to care about employees' opinions. As a result morale is low, and the culture is depressing. Not given sufficient time to fix problems, so everything is a fire that has to be put out, and once you have put a patch on it you must hurry to the next fire. Too many customers for current company structure, that along with little pay makes for a very stressful environment that causes high turnover among employees.
