Using Blackbird During Zoom Interviews
Zoom is where most technical and behavioural interviews actually happen, usually with a screen share halfway through.
What Zoom shows the other side
- —Your webcam feed and audio
- —Whatever you choose to screen share
- —Cloud recordings of both
- —Nothing about your running applications
- —No keystroke or process telemetry
How Blackbird fits in
Zoom shares a window or a display through the OS capture pipeline. Blackbird is excluded from that pipeline, so both a full-screen share and a single-window share come through clean.
Blackbird is a lightweight native Windows overlay drawn at the system compositor level. It is not a browser tab, an Electron window, or a shared surface, so it does not show up in screen recordings, screen-share streams, or active-window checks. It stays on top, accepts clicks without stealing focus, and disappears instantly with a hotkey.
Practical tips
- +Position the overlay next to your camera so your eye line stays natural.
- +Speak in your own words rather than reading sentences.
- +Test a share with a friend once before a real interview.
- +Keep the overlay narrow so you can scan it quickly.
Frequently asked questions
Does Blackbird appear in a Zoom screen share?
No. Zoom receives the display without the overlay, whether you share a window or the whole screen.
What about Zoom cloud recordings?
The recording is made from the same stream, so the overlay is not in it.
Can Zoom see it as a running app?
Zoom does not report your running applications to the host.
Does it work with Teams and Google Meet?
Yes, the same exclusion applies to Teams, Meet, Discord, OBS and Game Bar.
You are responsible for following the rules of any exam, employer or institution you use Blackbird with. No tool can account for human observation or behavioural review.
