I applied through an employee referral. The process took 3 months. I interviewed at PLEX (MD) (Fort Meade, MD) in Jun 2019
Interview
Pretty standard federal services process. Show the resume, proves the clearance, demosntrate the degree, certs, and experience. Basically get your resume lined up with the PD/LCAT. It's the government services industry, everyone wants to get you hired.
