I am in the same boat as you, sortof. I am also going through the security clearance process and will be hoping to start my job as an Army civilian contractor shortly thereafter. I am preparing for a UA (been clean over a month) and should have no problem passing it, but did they mention anything about a hair follicle test to you? I am also preparing for that just in case, but really hope it doesn't come to that. Your insight is much appreciated.
