Hyroo

AI hiring governance

How automated candidate scoring is controlled, recorded and audited
Sign in
Hyroo scores applicants to help a recruiter decide reading order — with an AI model where the deployment has one configured, and with deterministic rules where it has none. The score never advances, rejects, hires or messages anybody. Every score — including the ones produced with no AI model at all — is written to a decision log that records which model and which version of the scoring instructions made it, and every time a human decided against it.

The tool is advisory, and cannot act

The score changes what a recruiter reads first. It changes nothing about a candidate's status.
No automated action, in any configuration
No stage change, rejection, hire or message is ever driven by a score. Every state transition is performed by a named person. There is no setting, plan or switch that makes the tool advance or reject anyone.
A score is a similarity judgement, and is described as one
It compares a résumé against a job description. It is not validated as a predictor of job performance, tenure or retention, and we make no such claim.
Disagreement with the tool is recorded, not discouraged
Advancing someone the tool did not recommend, rejecting someone it did, hiring against it, or an interview verdict contradicting it — each is captured with the actor and the before/after state, at every decision point in the pipeline.

What the model is never given

The controls are structural: most of what could bias a score does not exist on the record to leak.
Not the candidate's name field
A name is a well-known proxy for gender, ethnicity and national origin. The dedicated name field is omitted from the scoring prompt, but résumé text may contain identifying information: the prompt carries the opening of the résumé, where a name, an email address and a phone number usually sit. Stated precisely, because the distinction matters: the control is on the prompt, not on the text. A name written inside the résumé itself can still reach the model, and is mitigated by instructing the model to ignore it rather than prevented structurally.
Not a protected attribute — there is none to give it
There is no gender, race, age, date-of-birth, religion, disability, veteran, marital or photo field on the candidate record. Where a workspace chooses to collect voluntary self-identification for fairness testing, it is stored in a separate table that the scorer has no path to reach; recruiter screens show it only as aggregates, and only the organisation owner's export of the whole workspace contains the individual answers.
Not the contact fields
The dedicated email and phone fields are not part of the scoring input — though, as above, the résumé text the model does receive may contain them.
And the prompt says so out loud
Every scoring prompt instructs the model to judge job-relevant merit only and to ignore any protected signal that leaks through free text. This mitigates indirect proxies in a résumé — a university, a country, a career gap — it does not eliminate them, which is exactly why the statistical testing below exists.

What is recorded about every decision

The log is not a feature you buy; it is written for every workspace, always.
One record per automated decision, written once and never rewritten
Which candidate, which job, which model, which prompt version, the score, the band, the merit signals the model actually saw, and its rationale with contact details and names stripped out. No part of the product changes what a decision says once it is written. Two paths touch one again: merging two records of the same candidate moves both records' decisions onto the one that survives, and erasure deletes them with the candidate.
Including the decisions made with no AI at all
When the AI is switched off, the spend cap is reached or the model call fails, a deterministic fallback produces the score. That is still an automated employment decision, so it is logged as one — recorded as having had no model and no prompt.
No off switch, no plan tier, no flag
An audit trail with gaps in it cannot answer the only question that matters: how was this person scored. So there is nothing to turn off.
The prompt version is a fingerprint of the prompt's wording
Not a number somebody remembers to increment. Change one word and past decisions stay attributable to the wording that produced them. That is attribution, not replay: the filled prompt and the model's answer are not kept, so a past score can be traced to its wording but not re-run.
It commits with the score
The explanation is written in the same database transaction as the score, so a score can never exist without one.

What the fairness audit measures

Two halves, because only one of them works without asking candidates for demographic data.
Process fairness — needs no demographic data
The distribution of scores, which model and prompt version produced them, the share produced with no model, and the rate at which humans decided against the tool. No demographic data is required for any of it. A near-zero override rate is itself a finding: it suggests the humans are rubber-stamping.
The report itself is a pilot we switch on for a workspace
The decision and override logs are written for everybody, always. The report that reads them is a pilot we enable workspace by workspace — off by default, and off in our production deployment until its gates are closed — and the statistical half needs data that has to be collected separately. A workspace without it still has the log; it does not yet have the report.
Statistical adverse impact — opt-in, and off by default
The four-fifths test compares selection rates between demographic groups, and we hold no demographic data. Inferring it from names or photos would be both unlawful and the exact bias that omitting the name field is meant to reduce. So a workspace may choose to invite voluntary, consented self-identification — a decision to take with legal advice, and one some jurisdictions constrain.
Small groups publish nothing
A group of fewer than 5 people has its counts, rates and ratio removed entirely, and is excluded from comparison. A ratio computed on three people swings on a single decision and can re-identify individuals; a number there is worse than no number, because it reads as evidence.
And the surrounding totals are coarsened too
When any group is withheld, the headcounts beside it are withheld and coverage is banded, because an exact total published next to the reported groups lets a reader recover the withheld one by subtraction.
Every ratio is read against its coverage
Self-identification is voluntary, so each table states what share of the scored population it was computed over, and low coverage is flagged on the report page. Where there was no scored population at all, that share is withheld rather than published as 0%, because a zero there would read as "we asked and nobody answered". A ratio over a small fraction of applicants is not evidence, and presenting one without its coverage is the easiest way to mislead with this report.

What a candidate can ask for

The rights the log exists to make answerable.
An explanation of a decision
Every automated decision made about them, the model and prompt version behind it, the merit signals it used, and the human decisions that followed.
Erasure that reaches the audit trail
Decisions, overrides and any self-identification are erased with the candidate. An audit record's instinct is to survive; here it is deliberately overridden, because every one of those rows is about the data subject.
A human review, or an alternative process
Every applicant is told before they apply that their application is scored by an automated tool, and is given an address to ask for a human review, an alternative selection process or a reasonable accommodation, or a copy of the automated assessments made about them. The address is the employer's own, or ours until they set one.

NYC Local Law 144 Annual bias audit by an independent auditor The exported workbook is the input an auditor works from — selection rates and impact ratios by category, with suppression applied. Engaging the independent auditor stays with the employer
NYC Local Law 144 Published summary of results The workbook's summary carries the scope, window, selection rule, threshold and the finding
NYC Local Law 144 Candidate notice before use An automated-tool notice to every applicant at application time, enumerating what the tool is given and naming an address for an alternative process, with room beneath it for an employer to add its own jurisdiction-specific wording. The lead time, and whether that wording is enough under a given law, stay with the employer

What we do not claim

Every statement above is bounded by these. The four-fifths threshold is 0.80 and the minimum reportable group size is 5.
• We do not certify the tool as unbiased, and the report is built so that it cannot say so. The strongest finding it can publish is: "No reportable group fell below the four-fifths (80%) threshold in this window." The absence of a signal is not proof of the absence of bias.
• We are not your independent bias auditor, and this does not replace one. NYC Local Law 144 requires an independent audit; we produce the evidence it is performed on.
• Showing a candidate notice at application time does not by itself satisfy a notice-period requirement, and the wording we ship names no law: it is jurisdiction-neutral. An employer may add its own text beneath it; we do not write that text and do not check it against any law. Timing, and whether the result is enough for a given jurisdiction, are the employer's duty.
• We do not claim the score predicts job performance, tenure, culture fit or salary. It has never been validated against on-the-job outcomes.
• We do not claim to eliminate bias. Omitting the name field and instructing the model on merit are meant to reduce it; a résumé is free text and can still carry the candidate's name, contact details and indirect proxies we cannot fully neutralise. That residual risk is the reason the statistical testing exists.
• This governance layer measures the scoring; it does not change it. The same prompts, the same model and the same scores as before it was added.
• Adverse-impact testing does not work out of the box. Without voluntary self-identification no four-fifths ratio can be computed at all — and the report says exactly that, rather than showing a clean result.
• Per-job adverse-impact testing usually returns "insufficient data". Most individual requisitions never reach the minimum reportable group size. That is honest, not a defect.
• Self-identification is voluntary, so respondents may not be representative of the applicant pool. Read every ratio against its coverage.
• A model or prompt change alters scores. Recording the model and prompt version on every decision makes that visible in the audit; it does not prevent it.
• Not every AI ranking in the product is an automated employment decision. Two are deliberately excluded from the decision log: copying a score that was already recorded, and the display ordering of external sourcing prospects, who have no candidate record for a decision to be about.
This is evidence you can hand to an auditor or a regulator. It is not the audit, and it does not make anyone compliant: the independence of a bias auditor, the timing of candidate notices, and the decision to collect demographic data at all remain the employer's, under their own legal advice.
