Pros
Salary and vacation package is generous.
Cons
Luck of the draw in terms of which team one is hired or move to. A bad boss means no promotion, no feedback, left in limbo at the client site, not protected against bullying/harassment by customer. In my case I was assigned what turned out to be a very dysfunctional organization that within the year had replaced its own senior management and treated its contractors like trash or worse (self included). My immediate supervisor, a nice competent man but worried about his own promotions/rise etc, did nothing to protect us at the site. His boss --my hiring boss-- was a complete a-- who was so full of himself that he had zero interest in his minions except for his few pets. But what particularly struck me as red flag, was how during a week's orientation, as we were being indoctrinated on the privileges of working for such an esteemed company, I noted (and raised a fair question) that it appeared the BAH's immense success was tied to its one sole customer, the US Govt. I asked is this was perhaps a risky model i.e. all eggs in one basket and what if this funding source dried up (this was asked circa 2009)? Wouldn't it be prudent to branch out a bit? Needless to say, my question/comment wasn't appreciated. This should have been another red flag.
