What level of a position are you trying to get?
I've been with government contractors for years - NG, SAIC, and now a small consulting firm for 5 years. Never had issues.
Many positions with these companies just require that you are clearable, not already have a clearance. Are you clearable? Would the government have reason to deny you an interim secret clearance (drug use in the past 7 years or other red flags)?
I would imagine it is certainly harder right now. But companies like BAH, TCG, SAIC, CSC are hiring. From my experience working on proposals in the past year or so, these companies are really under bidding their proposals so they are forced to hire more junior people to stay under the ceiling.
