Soon, video conference software will have “anti-cheat” features at parity with Steam and video game consoles.

There is already a huge anti-cheat industry built around college-level testing and certifications. Even live, remote proctors to watch and flag anything “suspicious”. So build it into Zoom and Teams with hooks to detect third-party add-ons, and whatever the dude runs on his own computer will be detectable to the remote side.

Folks will just intercept webcam feeds to spoof their eye movements and cheat on another device.

Fundamentally, companies cannot avoid the expense of flying candidates on-site and interviewing them in person anymore. It's kind of a miracle they ever could.

Some remote home testing software also requires connecting a second camera so that a proctor can watch the user and their screen. Now in theory it might be possible to intercept and modify that video stream in real time to filter out evidence of cheating but that would be quite difficult to do with high fidelity.

I remember a few horror stories of false positives.

Moreover, when I think I like to look at the ceiling instead of the screen, and I remember someone got accused of cheating for something similar.
