Blackbird for Campus Placement Assessments
Campus hiring drives are high-volume, heavily timed and delivered through Mettl, AMCAT, HirePro, HackerRank or the company's own platform.
What these drives monitor
- —Secure browser lockdown on most platforms
- —Webcam snapshots and face-presence checks
- —Tab-switch counting with automatic submission after a few switches
- —Section timers with no going back
- —Post-test similarity comparison across candidates
How Blackbird fits in
These assessments punish window switching hardest — several platforms auto-submit after two or three tab changes. That is exactly the action an overlay removes.
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
- +Never alt-tab; several platforms auto-submit on the third switch.
- +Watch the section timer — aptitude sections move fast.
- +Keep your face visible and centred for snapshot checks.
- +Rewrite code in your own style to avoid similarity flags.
Frequently asked questions
Does it work with TCS NQT and similar drives?
Yes. These run on standard proctored platforms whose monitoring is browser events plus webcam snapshots.
Will the secure browser block it?
Secure browsers enforce kiosk mode and check for known applications; a native overlay drawn above them is not in scope.
Are aptitude sections supported?
Yes — screenshot the question and read the working on the overlay.
Is the free tier enough for a full drive?
Usually not; these run well past 15 minutes, so Pro or the one-time $20 month is the practical choice.
