Just a short post for now, but one of my "fans" in the comment section mentioned that getting a federal government job is actually pretty difficult even if it's for a non-legal position.
I think he's pretty much correct. The people I do know that have been successful getting into "government" work have been government contractors.
There are positions all over the country (none really seem to be legal positions), but the bulk are in the DC metro area.
I don't think they qualify for the public interest loan forgiveness under IBR because you're working for a private company that has a contract with the government.
While, the federal government has USAJOBS for federal government positions, there isn't an equivalent system for contractor jobs.
The Washington Post, however, has a pretty good listing of contractor jobs. If it's something you're interested in, you should check out this resource. You can even search for jobs in your area.
