Here's the real problem with running an AI interview assistant during a live call: you want it clearly visible to you, but you absolutely do not want it appearing in the region you screen-share. When an interviewer asks you to walk through code or a document, your shared view becomes public — and an overlay sitting in the wrong place goes public with it. So the question of where to position the AI interview assistant overlay is not a cosmetic one. It is the single decision that determines whether your setup is private or exposed.
The good news: this is a layout problem with clean, honest answers. No tricks required — just an understanding of what screen-sharing actually captures, and where to put the window so it falls outside that capture. Let's walk through it.
The single most important rule: share a window, not your whole screen
If you remember one thing, remember this: share a specific application window, not your entire screen or monitor. When you share a window, the meeting platform captures only the pixels belonging to that one app. Anything outside that window — including your assistant overlay — is never sent to anyone. It is genuinely impossible for the interviewer to see it, because those pixels were never transmitted.
Contrast that with sharing your entire screen. In that mode every pixel on the display is broadcast, so an overlay sitting anywhere on that monitor is captured along with everything else. This is the honest core of the whole topic: positioning works because window-share excludes everything outside the chosen window. There is no magic involved.
All three major platforms support this:
- Zoom: in the share dialog, pick the specific application window (your IDE, your browser, the doc) instead of the "Desktop / Screen" tile.
- Microsoft Teams: choose "Window" and select the single app, rather than "Screen."
- Google Meet: choose "A Window" (or "A Tab" for browser content) instead of "Your Entire Screen."
Do this and the overlay can sit anywhere outside that window with zero risk. We go deeper on this in our guide to using AI in a Zoom interview.
Best option: put the overlay on a second monitor
If you have two displays, the placement question is almost trivial. Share the window (or even the screen) on monitor one, and keep the assistant overlay on monitor two. Because you only ever share a single display or window, the second monitor is physically outside the capture. You can keep the overlay large and easy to read without any worry about it sneaking into the shared view.
This is the most forgiving setup: even if you accidentally share an entire screen, you've shared the wrong screen for the overlay to appear on. For anyone interviewing regularly, a cheap second monitor is the best money you can spend on your setup.
Quick check: drag the overlay fully onto the non-shared monitor — not straddling the bezel. A window that spills across both displays can clip into the shared one. Keep it comfortably inside the second screen's edges.
One-monitor setups: position outside the shared window
Most people interview on a single laptop screen, and that's completely workable. The approach is the same logic applied within one display:
- Share a window, never the full screen. This is non-negotiable on one monitor — it's what creates a "safe zone" for the overlay to live in.
- Park the overlay outside the shared window's bounds. Shrink the shared app to leave a margin, and place the overlay in that margin — a side strip or the area near the top of the screen.
- Use the desktop app's display controls. CoPilot Interview's Ghost Mode keeps the window off captured output and gives you opacity and position controls, so you can place it discreetly and tune it to be readable without dominating your screen.
- Keep it near your webcam. Positioning the overlay close to the camera means your glances stay short and your eye-line stays natural — more on that next.
Note that Ghost Mode is a privacy-respecting display layer, not a way to defeat an assessment. It still pairs with window-share; the two work together.
Eye-line: stay engaged while you glance
Where you put the overlay also shapes how you come across. A window jammed into the bottom corner pulls your eyes down and sideways — visible, and a little distracting. The fix is placement plus discipline:
- Place it directly under or beside your webcam. A glance then lands near the camera, so it reads as a natural pause for thought rather than a darting look.
- Keep it compact. A smaller overlay means less scanning and shorter glances.
- Lead with your own answer. Start talking from your own knowledge, and check the overlay only when you genuinely stall.
- Return to the camera. After a glance, bring your gaze back so you stay in conversation with the interviewer, not with your screen.
What the interviewer sees vs. what you see
Let's be plain about this, because it's where the honest line sits. The interviewer sees exactly the pixels inside the region you chose to share — nothing more, nothing less. You, locally, see your full desktop including the overlay. The overlay stays private not because it's hidden from a camera, but because it lives outside the shared region.
And the flip side, stated plainly: no tool can hide an overlay from screen capture if you literally share the pixels it occupies. If you share an entire monitor and the overlay is on that monitor, it will be captured. That's not a flaw in any app; it's how screen-sharing works. This is exactly why positioning — share a window, or use a second display — is the whole game.
| Setup | What you share | Overlay placement | Result |
|---|---|---|---|
| Two monitors | Window or screen on monitor 1 | Monitor 2 | Safest — outside capture |
| One monitor, window-share | One app window | Outside that window | Safe — not captured |
| One monitor, full-screen share | Entire display | Anywhere on it | Exposed — avoid this |
Platform-by-platform quick notes
Zoom
Zoom's window-share is reliable and clearly labeled. In the green share menu, individual application windows appear as separate tiles — pick the one you need, not the "Screen" tile. If a new window you open mid-interview doesn't show up in the share, that's expected: window-share only sends the window you selected.
Microsoft Teams
Teams separates "Screen" and "Window" in the share tray. Choose the specific window. One quirk: certain pop-up dialogs from the shared app may not render to the viewer; if you need a dialog visible, you may have to share the screen for that moment — so move the overlay to a second monitor first, or close it, before doing so.
Google Meet
Meet offers "Your Entire Screen," "A Window," and "A Tab." Pick "A Window" for desktop apps or "A Tab" for browser-based exercises — both exclude everything else, including your overlay. Tab-share is especially tidy for online coding pads, since only that one tab is sent.
A note on policy
Positioning your overlay correctly is about privacy and a clean setup — not about hiding from rules you've agreed to. Respect your employer's or the interview's stated policy on assistive tools. Many conversational rounds are fine with discreet support; some assessments forbid outside help entirely. When it's unclear, ask the recruiter. Using the tool to prepare and to steady your nerves is always above board; positioning simply keeps your screen-share clean and professional. See our desktop vs web AI interview assistant comparison for why a desktop app gives you these display controls in the first place.
Position it perfectly in seconds
CoPilot Interview's Ghost Mode keeps the overlay off your shared screen, with opacity and position controls so you can place it right by your webcam. Free for Windows and macOS.

Will the interviewer see my AI assistant overlay?
Only if the overlay sits inside the region you actually share. If you share a single application window, anything outside that window is never captured, so the interviewer never sees it. If you share your entire screen or monitor, every pixel on that display is sent, including the overlay. The honest rule is simple: positioning, not magic, is what keeps the overlay private — keep it out of the shared region.
Do I need two monitors to position the overlay safely?
No, but a second monitor is the easiest setup. With two displays you put the shared window on one screen and the overlay on the other, and the overlay is physically on a display you are not sharing. On a single monitor you can still keep it safe by sharing a specific window rather than the whole screen, and by parking the overlay outside that window's bounds.
What is Ghost Mode?
Ghost Mode is the CoPilot Interview desktop feature that keeps the assistant window off captured and shared output, combined with opacity and position controls so you can place it discreetly near your webcam. It is a privacy-respecting display layer, not a way to defeat a test — you should still share a window rather than your whole screen, and still follow any rules about assistive tools.
Can I use the overlay if I share my whole screen?
If you literally share an entire monitor, any overlay on that monitor is captured along with everything else — no tool can hide pixels you are deliberately transmitting. The safe approach is to share a single application window instead, or move the overlay to a second monitor you are not sharing. Window-share is supported on Zoom, Microsoft Teams, and Google Meet.
How do I keep my eye-line natural while glancing at the overlay?
Place the overlay directly beneath or beside your webcam and keep it compact. That way a quick glance reads as a normal pause for thought rather than your eyes drifting to a corner of the screen. Lead with your own answer, glance only when you stall, and return your gaze to the camera so you stay engaged with the interviewer.
