I have held a security clearance of some type for more than half of my life. I've lived and traveled a bit overseas and and been friends with foreigners here and abroad. As of last Tuesday I am on my fourth company for the same job I've held for ten years, (hired, company bought, contract lost and position transferred to the winner, company bought) though I changed employers intentionally a lot more in my youth.
Reinvestigation interviews are getting longer and harder to keep everything straight through.
Someday I won't have to do this anymore.
