Using the LastRound AI interview copilot? Test the overlay here
- Start the test above and choose Entire screen.
- Open the LastRound AI desktop app (Windows or Mac) and start the overlay.
- Drag the overlay on top of this browser window.
- Look at the preview: if it shows this page where the overlay sits, the overlay is left out of the share.
The overlay asks Windows (10 version 2004 or later) and macOS to leave it out of screen capture. It cannot hide anything outside the video stream, such as a camera pointed at your monitor. See what it hides and what it does not.
Download the desktop app (Windows / Mac)How the screen share test works
When you click Start the test, your browser asks the operating system for the same screen stream that a video-call app gets: Windows Graphics Capture on Windows and ScreenCaptureKit on macOS. The page plays that stream back to you in the preview box. What you see there is what the other people on a call would see.
Everything happens inside your browser. The stream is never uploaded or recorded, and when you click Stop sharing (or close the tab) it ends. A snapshot is a still frame kept in the page until you download it or leave.
Apps can ask the operating system to leave a window out of screen capture. Password managers, some banking apps and interview copilots do this. If such a window is open, it is simply missing from the preview, and you see whatever is behind it.
Example: checking before a Teams interview
Priya has a Teams interview at 10:00 on her Windows laptop. At 9:45 she opens this page, clicks Start the test and picks Entire screen. The preview shows a Slack notification sliding in and her personal email open in a second tab.
She turns on Do Not Disturb, closes the email tab and runs the test again. Then she opens her notes window and drags it over the browser: the preview still shows the browser, so the notes window is not in the share. She ticks all five checks and joins the call.
Tips for better results
- Run the test on the same computer, monitor and browser you will use for the interview.
- Always pick Entire screen. If the interviewer asks you to share, many people share one window instead, which is even safer for privacy.
- Turn on Do Not Disturb (Windows: Focus, Mac: Focus or Do Not Disturb) before the call, not during it.
- With two monitors, the share shows only the one you pick. Test each monitor you might share.
- For a high-stakes interview, also do a 30-second test call with a friend on the real app.
