Dumb question but where do you apply for "government jobs?"

Sorry for the dumb question.

Law school seems to push either Big Law or public interest, both of which I am familiar with. But a growing number of seasoned attorneys have been telling me that too many people overlook "government jobs."

I know you work for the government... but where do you start to look for it? Is it the DOJ or broader? Where do I start?

Just looking for some places to start
