What's worse than not being able to find a job.....is being offered a great job, then have it rescinded because you don't pass the security check.

Due to an isolated lapse of judgment I made almost 15 years ago, the security clearance didn't go through for me, though I have no criminal background, have great credit, a stable family history, and I had a great interview. They offered me double what I make now. I guess some mistakes dog you til the day you die. At least now I know to not apply for jobs which require security clearances. You'd think, though, that cleaning up your act over a period of years would rectify things. Not so. Big bummer.
Maybe this will help someone else out in some way, since a lot of networking jobs require a security clearance.
