## FAQ

**Can an AI recruiter replace an ATS?**

Not for most teams. An AI recruiter can find, contact, qualify, and schedule candidates. An ATS remains the better system for formal applicant records, interview feedback, permissions, offers, dispositions, retention rules, and reporting.

**Can an ATS replace an AI recruiter?**

Only when candidate supply is already sufficient or the ATS includes sourcing and engagement functions that perform well on the company's roles. Applicant tracking alone does not create a passive-candidate pipeline.

**When should a candidate enter the ATS?**

The cleanest point is when the candidate has shown credible fit and real interest and is entering the employer's formal interview process. Companies may create records earlier for policy or reporting reasons, but ownership should remain clear.

**Do small companies need both?**

Not always on day one. A company with strong inbound volume may begin with an ATS. A founder hiring one hard role may begin with an AI recruiter and a simple formal record. Repeated hiring with several interviewers usually creates a need for both capabilities.

**What data should an AI recruiter send to the ATS?**

Send identity and contact information, source, role, fit evidence, outreach and reply context, screening notes, unresolved questions, scheduling data, and policy-required consent or retention information. Avoid flooding the ATS with low-value system events.

**Who is responsible for the hiring decision?**

The employer. AI may assist with criteria, search, ranking, outreach, screening, and scheduling. The employer must verify evidence, run a fair process, provide required accommodations, interview candidates, and decide.
