"Interview" occurred on a Friday. Most gov't production facilities run pretty slow on Fridays. I was impressed by the amount of individuality civilians get to express. Lenient dress code, facial hair of all types are welcomed. Be ready to provide license, registration and proof of insurance for your vehicle upon trying to enter, even if you are already on the "approved" list for entry. Hiring authority seemed disinterested in my skill set. Just cared that I had credentials.
