Pros
I work in the DC area supporting a government contract and have had a great experience. The crew in the DC office has a deep understanding of government contracting and makes sure you know exactly what you are getting into and signing up for. They seem to have great empathy as they were able to understand my concerns without me really bringing them up. They did not pressure me (which happens a lot with other companies) to join the company. They did not try to "sell" me on their position. In fact, they pointed out both pros and cons/potential risks of the position, which I appreciated. The pay well and on time (as long as your time is approved). They are a company that cares about their people and takes care of them. I'm happy I took their call!
Cons
Benefits are expensive. They will reimburse for certifications, but only if the contract requires it.
