I think USAJOBS does a lot of things right.
Some problems I faced when looking for jobs at USAJOBS
-Lots of noise and lots of jobs....How do I filter to find the best ones? Either the ones with best promotion potential, most # of openings, etc
-Hard to know what it's really like in that specific division. Often you apply for a job and you vaguely know about DHS but what you really need to know is if the DHS/ICE/OCIO/IT Security division is cool
What other problems do people face?
