Zoom interview overlay: what they see, and how to test it

An overlay is a small window that floats on top of your other windows, including a full-screen Zoom call. An AI interview overlay shows you notes or suggested answers while you talk. It is a window on your own computer. It is not part of Zoom, and the people in the meeting do not get it.

So the real question is not "can Zoom see the overlay?" but "what does Zoom send to the other side?" Zoom sends your camera and microphone and, only when you press Share, a picture of what you chose to share. The sections below go through each one.

From Zoom's own help pages, checked on 17 and 18 October 2026:

• Nothing is shared until you press Share. Zoom says: "Meeting hosts cannot monitor your screen activities unless you choose to share your screen."
• You choose what to share. In the Screens tab you can share your entire screen or one or more application windows. Under Advanced you can share a portion of your screen, shown with a green border.
• Share one window, and only that window is sent. Anything else on your screen, an overlay included, is not part of that share.
• Share your whole screen, and everything on it is sent, unless a window is kept out of screen capture. Zoom does this for its own windows: "By default, the Zoom window is not shared while sharing your screen."
• Zoom has more than one way to capture a screen. In Settings, Share Screen, Advanced, the screen capture mode can be Auto (the default), capture with or without window filtering, or a legacy mode for older systems. Zoom notes that changing it can change what gets shared.
• The host may control sharing. A host can turn participant sharing on or off, so you may be asked to share, or not be able to.

What this means for an overlay: if you share one window, the overlay is not in the share anyway. If you share your whole screen, what matters is whether that window is kept out of screen capture.

Do this a day or two before the interview, on the computer you will use. It takes about ten minutes. Zoom's test meeting at zoom.us/test checks your camera, speaker and microphone, but nobody else is there to see your share, so you need a second person or a second device.

1. Start a Zoom meeting and bring in a viewer. Ask a friend to join from their computer, or join the same meeting from your phone under another name. If you use your phone, mute it and turn its speaker down to avoid echo.
2. Open the overlay where you will keep it on the day, and put some text in it.
3. Share your entire screen. Ask what they see, or look at your phone. They should see your desktop and the Zoom call, not the overlay.
4. Share one window, for example your browser. They should see only that window.
5. Record and play it back. Start a local recording while you share your screen, stop it, and watch the file. Zoom says recordings can include shared content, and local recording works on free accounts too, if the host allows it.
6. Use the same settings as the day. The same Zoom app or browser, the same screen capture mode (Settings, Share Screen, Advanced), and the same monitors. Zoom says changing the capture mode can change what is shared.
7. Check from the app too. In ClapAssist, open Settings, General, and press Test next to "Test it". You want: "The bar was hidden. Screen recording can't see it." You can also share your whole screen inside the screen share check page and look for yourself.

If anything in steps 3 to 5 shows the overlay, stop and use the fixes below before the interview.

On a Mac

• Two apps need permission. Zoom (or your browser) needs Screen & System Audio Recording to share your screen. ClapAssist asks for the Microphone and for Screen & System Audio Recording, to hear the interviewer and read a question on your screen. You turn each one on in System Settings, Privacy & Security.
• Restart after allowing. macOS gives an app a new screen permission only after it restarts. ClapAssist shows a Restart to finish button.
• The window is marked as not shareable, so a whole-screen share and a screen recording leave it out. Our Mac guide covers the permissions step by step.

On Windows

• Use Windows 10 version 2004 or later, or Windows 11. The Windows setting that leaves a window out of capture arrived in that version. On older versions it shows the window as an empty box instead.
• Hardware acceleration for screen sharing is a Windows setting in Zoom. Zoom says to turn it off if people have trouble seeing your shared screen.
• More in our Windows guide.

That is the employer's call, not ours and not Zoom's. Some employers say AI help is not allowed in interviews. Some say nothing. Some expect it. Read the invite, and ask if you are not sure. If the rules say no, do not use it.

What happens to your data: live call audio and screenshots are used to make the answer and are never stored. Your resume, notes, the written recap and the interview transcript are saved to your account so the app fills them in on any computer. You can switch transcripts off in Settings and delete any of it any time.
