Interview for Network Engineer – Government Contracting (DoD/Navy) The process took about 2½ weeks from recruiter contact to offer. First was a quick phone screen to verify my active Secret clearance, required certifications (Security+, CCNA), and willingness to travel 50–60%. The technical interview over video covered Cisco switching/routing, wireless troubleshooting, firewall rules, VLANs, and DISA STIG compliance. A short call with the government program manager followed, focused on communication skills and prior secure-environment work.
