Most hiring tools track candidates. Exterview **evaluates** them, and the AI agents that assist them, consistently, reproducibly, and with a full audit trail. It's an intelligence layer that sits above your existing ATS, not a replacement for it. ## What Exterview is, and isn't A system of specialized agents that run and score evaluations across the hiring lifecycle. It doesn't replace your pipeline tracker, it makes the decisions inside it better. Calibrated to your roles, your rubrics, your bar, not a generic industry model. It learns from your outcomes over time, rather than serving one fixed model to everyone. ## The thesis, in three lines Evaluations are grounded in your structure and standards. Every cycle sharpens your calibration, an advantage only you accumulate. Post-hire outcomes are designed to feed back into better future evaluations. ## Where to go next The pillars behind the moat. The hard buyer questions, answered. The mental model and vocabulary. ## FAQs Agentic talent intelligence, an evaluation layer above the ATS, not another applicant tracker. No. Exterview works above your existing stack and integrates with it. It's calibrated to your roles, rubrics, and outcomes, and specific to your organization, it isn't a shared model. ## Related The Configure, Deploy, Monitor lifecycle in practice.
