Pros
1) If you're willing, you can learn a lot. 2) Once you work ++ hours there's an excellent sense of camaraderie. 3) Eager workforce 4) Most people honestly are doing there best to make this place work. 5) Managers will try to teach you if you work hard enough to track them down, but this is sometimes difficult.
Cons
1) Several times if I told HR something seemingly in confidence, within moments my supervisor would pull me into their office to discuss the matter. 2) Rarely will you find someone who has work/life balance, I pulled some obscene (100 hour) weeks. This depends on who you work for and what project your on, and what you do some people work 40-50 hours, some people are on the phone with management until 3 am routinely. I wouldn't risk it again. 3) There is no process. Work just flys around in a half hazard manner, and whatever is getting the most pressure gets worked. 4) As a result of the amount of work to be done it's infrequent that you're congratulated on the work you did meaningfully, such congratulations will usually come when you've performed some simple task quickly as opposed to completing a massively long drawn out task that received high viability but was never scoped properly for a level of effort. 5) Speaking of level of effort, you will usually not be asked for one, someone up the chain will decide that X or Y task takes X or Y days, promise it to the customer regardless of contract deliverables, and regardless of the work you're already doing, they will start bothering you for completion. 6) Management. They have supervisors more than managers, Technical people who are more advanced at what they do get promoted to lead, when management and technical skill are two entirely different things. As a result Management niceties like scheduling and planning, process and documentation, cross training, training AT ALL tend to suffer.
