I applied online. I interviewed at Defense Commissary Agency (Augusta, GA) in Jul 2016
Interview
Apply online at USAJobs, if selected they will send you a offer letter with amount they are willing to pay. You are required to accept or decline the offer to move further in the hiring process.
Submitted resume and requested supplemental documents via UsaJobs. There was no interview. They called about three months later and asked if I wanted the job. I was not impressed with their selection process.
