The Ghost in the Machine: Detecting Deepfake Proxy Candidates
Recruiting has entered a new, darker chapter. Real-time deepfakes aren't just a gimmick anymore—they are actively infiltrating the technical hiring funnel. Here is what we're seeing on the front lines.
"He looked like the guy in the passport. He spoke like a senior engineer. But four minutes in, my gut felt something was wrong. The mouth was just... off."

Last year, "proxy interviewing" meant someone else was whispering answers into an earpiece. Today, it’s a high-stakes tech-stack of its own. Using generative adversarial networks (GANs), bad actors are now injecting real-time video feeds into Zoom, Teams, and specialized platforms. They aren’t just helping candidates; they are the candidates.
At TalentLyt, we’ve analyzed over 50,000 interview hours. We don't just see pixels; we see the systematic patterns left behind by visual injection.
The 13-Signal Verification Stack
A deepfake proxy isn't a static image. It’s a dynamic mask. But even the best consumer-grade GPUs can’t perfectly replicate the complex physics of a human face during high-stress technical probing. We analyze 12+ signal types that human eyes often miss:
1. Phonetic-to-Visual Latency (The "Drip")
The brain processes sound and light at different speeds, but our speech muscles are biological clocks. Real-time neural re-rendering usually introduces a 150ms to 300ms lag. In a technical interview where speed of thought is key, this drift becomes a mathematical certainty for detection.
2. Neural Boundary Tearing
Watch the edges. When a proxy candidate moves their head suddenly or raises a hand near their face, the neural mask "tears." These are sub-pixel micro-glitches where the AI fails to map the depth of the occlusion. It looks like a shimmer to some; to us, it's a fraud alert.
3. Illumination Spectrum Mismatch
A deepfake might match the color of the room, but it often fails to match the specular highlights on the pupils. Real light bounces off an eye in a specific way; AI-generated light lacks the environmental consistency of the proxy's actual room.
The Legal & Ethical Wall
Detecting fraud isn't just about catching "bad guys"—it’s about protecting the true candidates who spent years honing their skills. However, this level of surveillance comes with a massive responsibility.
A Note on Privacy: As a recruiter or engineering leader, you must ensure that your integrity tools are compliant with GDPR, CCPA, and BIPA. At TalentLyt, we use "ephemeral processing." We don't build biometric databases; we analyze signals in real-time and discard the raw biological markers immediately after verification.
Always disclose that automated integrity verification is in use. Transparency is the best deterrent.
Why We Built Sentinel
We didn't build the Sentinel Engine because we wanted to be "Big Brother." We built it because we saw honest companies losing millions and honest engineers losing jobs to proxy actors. Our approach uses SyncNet and adversarial modeling to create a "Zero-Trust" environment for every interview.
The "resume check" is dead. The "video check" is dying. The only thing left that you can actually trust is verified, real-time behavioral telemetry.
Zero Trust for Technical Hiring
The era of "honest video" is over. Companies must adopt a zero-trust architecture for technical assessments to ensure they are actually hiring the person they saw on screen.
