I applied in-person. The process took 4 weeks. I interviewed at US Army (Charleston, SC) in Jan 2014
Interview
You just go through physical fitness test, and mental physical. To be apart of this profession, you must obtain at least an High School Diploma. If you are not physically fit, your recruiter will help you progress and get you where you need to be for basic training.
Long process multi day and multi event. Respond to USA jobs vacancy announcement. Submit packet. Archduke interview with little to no led time. Interview was pretty easy. Oral interview then on the spot written (in ink) responses to questions. Final determination is made on the condition of a clearance and a drug test.
