Pros
The office view is great. You run into some nice people. Benefits are pretty good for the area. Snacks, sodas, etc. are provided. You occasionally get some social outings with coworkers. Based on appearances, it has the feel of a progressive, modern company.
Cons
The reality is that the work is terrible. There seem to only be a small handful of clients they sell to, and most of the time, it's staff augmentation work. Developers and architects work with a lot of proprietary legacy technology which doesn't provide much in career value, unless you want to specialize in these legacy technologies. Their "core values" are a facade, they only apply if it ultimately gets them more billable hours. Their clients impose their will on the culture. This basically means if you're looking to leave a large corporate job for this company, you'll be thrust right back into a similar (if not worse) situation. Developers and architects are routinely thrown into situations where they are poorly supported and are forced to sink or swim. Often times, technologies are forced onto these folks that they don't specialize in or care to work. Morale is generally bad as a result, and turnover is high. Executive leadership is either blissfully ignorant or cares little about these matters, so long as everyone is billing.
