Pros
Great co-workers, nice facilities, fun and beneficial charity events and outreach programs. Most senior engineering and design staff members are great and willing to teach as long as you are willing to ask.
Cons
After 2012 no raises unless promoted, not even cost of living raises. Overtime required constantly, often for free. Management completely disconnected from staff supporting project. No clue what obstacles are faced on a day to day basis, and when raised to their attention you get an email sent if lucky, most times you just get told to do more work on top of normal deliverables, and technical issues often go ignored by management who just want to meet payment milestones and look good to client regardless of quality of work or whether it is done correctly or to code if it is going to affect schedule. Going "above and beyond" on projects, even value saving ideas saving millions of dollars on project are rewarded with small gift cards instead of project performance based incentives they promise when getting hired as direct employee. Work will keep getting piled on and on until you push back. A lesson I learned the hard way.
