Why zkML? Because @HumanlyHR just launched an updated conversational AI platform designed to automate chat qualification, phone screenings, and structured video interviews — enabling enterprise-scale hiring.
When AI is making first-line hiring decisions, verifying how candidates are assessed becomes critical.

This platform doesn’t just filter resumes.
It engages candidates via chat, conducts automated phone screenings, and runs structured video interviews — all built on a unified communication framework.
But when evaluation is driven by AI decisions, the core challenge shifts from processing volume to justification of decisions.

The issue: AI-driven hiring often functions as a black-box filter.
Recruiters see candidate recommendations, but cannot see:
- Which data points influenced the recommendation
- Whether assessment criteria were followed
- Whether the AI model applied correct logic
- Whether any drift or bias occurred
For scalable hiring operations, unverified reasoning is a systemic weakness.
4/
That’s where zkML matters:
✅Prove a candidate assessment was generated using the approved model
✅Prove which criteria guided the decision without exposing candidate details
✅Prove institutional policies were enforced in the reasoning chain
✅Enable auditors and HR teams to validate workflows without exposing internal logic
zkML transforms AI-driven hiring from automated filtering into verifiable decisioning.
5/
Hiring at scale is no longer about speed — it’s about trusted automation.
When AI evaluates thousands of candidates autonomously, proof becomes part of the hiring stack.
That’s what @PolyhedraZK is building: AI hiring pipelines where each decision can justify itself.
