InterviewWatch is a consent-first integrity platform for live remote interviews. A lightweight application monitors machine-level signals to identify potential AI assistance, desktop and web AI tools, hidden cheat overlays, remote-control software, suspicious typing patterns, virtual devices, and unusual display or clipboard activity. It never records the candidate's screen, audio, or video and does not capture typed or clipboard content. Signals appear in a real-time recruiter dashboard and are converted into an explainable integrity score and tamper-evident report for human review, helping employers verify that candidates are genuine and completing interviews independently without invasive surveillance.
