Lockbox is a tamper-proof coding interview platform that blocks AI overlays, detects unauthorized tools, and runs candidate code in isolated VMs. Get honest assessments of real engineering skill.
Every candidate runs code inside an isolated Docker container with no network access, read-only filesystem, and strict CPU/memory limits. No phone-a-friend possible.
Detects and blocks tools like ChatGPT, Copilot overlays, screen-sharing apps, and other unauthorized assistants running alongside the interview window.
Monitors typing patterns, paste detection, keystroke intervals, and code production rates. Bot-like or AI-generated input is flagged in real time.
Interviewers see the candidate's code in real time with syntax highlighting. Every keystroke, edit, and run is recorded for post-interview review.
Peer-to-peer WebRTC video and audio between interviewer and candidate. No need for a separate Zoom or Meet link.
Each session generates a risk score based on violations detected. Post-interview reports include violation timelines, behavioral flags, and code metrics.
Three steps to a cheat-proof interview
Interviewer logs into the dashboard, creates a session, and shares the Session ID with the candidate.
Candidate downloads the Lockbox desktop app, launches it, enters the Session ID, and joins the locked environment. All activity is monitored.
Interviewer views live code, security alerts, and behavioral data. Post-session reports help make informed hiring decisions.
