@Jonathan Gaines. Most Federal IT services have been outsourced to private contractors. Those contractors work along side federal workers, but are not considered federal workers.
Another reason you are not getting a response is because Veterans get preference, displacing other qualified candidates on entry level jobs.
If you are open to moving, try applying to remote and rural locations like Wyoming, Montana, Alaska, Dakotas, and Idaho. Be prepared to spend a few years in one of those locations, however. That will allow you to get full time federal status and apply to internal jobs.
