How Mercer Mettl monitors your session
Mercer Mettl is an AI-driven online assessment and proctoring platform widely used for hiring and remote exams. Understanding exactly what it watches is the first step to using a tool like Ofradr safely alongside it.
Mercer Mettl typically relies on a combination of the following signals to flag candidates:
- Webcam-based face tracking and identity verification
- Screen sharing and full-session screen recording
- Secure browser that blocks tab switching and copy-paste
- AI flagging of multiple faces, background noise, and gaze movement
Why Ofradr stays invisible to Mercer Mettl
Most "AI helpers" are Electron or browser-based apps that show up as a visible window, a new process, or a screen-share layer — exactly the things Mercer Mettl is built to catch. Ofradr takes a different approach.
Ofradr is a lightweight (~800KB) native overlay rendered at the system compositor level. It is not a browser tab or a shared window, so it does not appear in Mercer Mettl's screen capture, recordings, or active-window checks. There is no obvious process name, and the overlay can be toggled instantly with a hotkey.
Because the assistance happens off the captured surface, Mercer Mettl sees a normal, focused candidate while you read solutions, hints, and complexity analysis privately.
Practical tips for Mettl hiring assessments and proctored exams
Stealth tooling is only half the equation — behaviour matters just as much when Mercer Mettl is recording. Keep these habits in mind:
- Keep your eyes on the screen and avoid obvious glances away from the camera.
- Type your answers naturally instead of pasting large blocks at once.
- Read the suggested approach, then write it in your own words and structure.
- Run Ofradr offline with a local model when the environment blocks outbound traffic.
Frequently Asked Questions
Can Mercer Mettl detect Ofradr?
No. Mercer Mettl inspects shared windows, browser activity, and screen recordings. Ofradr renders as a native system-level overlay that is excluded from those capture paths, so it does not appear in Mercer Mettl's monitoring.
Does Ofradr work while Mercer Mettl is in full-screen lockdown?
Yes. Ofradr's overlay sits above the locked-down environment without interrupting it, so you keep full access to assistance even when Mercer Mettl restricts other applications.
Is Ofradr free to use with Mercer Mettl?
Yes, the Ofradr Community Edition is free. Unlike subscription tools such as Cluely ($20/month) or Interview Coder ($19/month), you can use Ofradr at no cost.
Does Ofradr need an internet connection during a Mercer Mettl session?
No. Ofradr supports local models like Llama and Mistral, so it can run completely offline. Your screen content and prompts never leave your machine.
