I applied online. The process took 3 days. I interviewed at Omniplex World Services Corporation (Chantilly, VA) in Sept 2016
Interview
There really wasn't a one on one interview. They do what is called a "Hiring Process" and they bring in 10 to 15 applicants and review all of your documents and paperwork. If they deem it suitable and the initial criminal check is good, then you move on.
