AI recruitment tools can process anything from the details on a CV to recorded interview answers or information found online—but no single data set applies to every tool. What is collected depends on the tool’s purpose and where it is used in hiring. The data may be organized, compared, scored, or used to rank candidates, affecting who advances to an interview or job offer.

What data can AI recruitment tools collect?

Recruitment software ranges from tools that organize applications to systems that assess candidates. A tool may use information supplied by an applicant, information about the role, records gathered from other sources, or attributes inferred from those inputs. These categories are possibilities, not a standard bundle collected by every employer.

Data category Examples How it may be used
CV and application details CV or résumé text, skills, education, qualifications, employment history, and answers to application questions A parser may extract and structure details; a matching or screening system may compare them with a vacancy or candidate profile. The ICO’s 2024 account and UK government recruitment guidance describe these uses.
Role and labour-market information Job requirements, occupational categories, and, in some systems, labour-market data Matching systems can use these details alongside candidate information to rank or match people to vacancies. The EU AI Act Service Desk’s examples describe this type of matching.
Assessment and interview content Written or spoken answers, test results, and recorded interview responses Systems may score responses or analyze them with automated language processing. A person may review the content, software may process it, or both may be involved. Canadian federal public-service guidance discusses AI-based assessment methods.
Online and background information Depending on the system, professional sites, social media, job boards, CV databases, education or professional records, and employment history Sourcing tools may look for candidates; background-check systems may aggregate records or create alerts. The EU service desk gives credit or financial information, where legally permissible, and online information as examples in a background-check scenario—not as routine collection by every employer. EU AI Act Service Desk examples are specific to the system described.
Inferences and indirect signals Attributes inferred from other data, or signals such as detected eye direction, facial expression, or tone of voice A system may use these as proxies for a characteristic or an assessment such as engagement. The ICO reported that some audited systems inferred gender or ethnicity from names; UK guidance discusses eye detection as an engagement proxy, and Canadian federal guidance gives facial expression and tone of voice as examples. These methods can produce inaccurate or unfair assessments. ICO findings, UK guidance, and Canadian federal guidance describe these concerns.

A video interview tool does not necessarily analyze faces or voices just because it handles a recording. Ask whether the system analyzes the video or audio, what signals it extracts, and whether a person reviews the recording or its output.

How is the data used in hiring?

The same piece of information can play different roles depending on the system. A CV parser may simply turn application text into structured fields; another system may use those fields to score, filter, or rank candidates against role criteria.

These outputs can influence who is shortlisted, interviewed, referred to an employer, or excluded. The European Commission distinguishes systems that materially affect candidate selection from more limited administrative uses, such as organizing CVs or scheduling interviews. See the AI Act Service Desk’s recruitment examples.

A human being able to view a score does not, by itself, establish meaningful oversight. The practical question is whether a reviewer consistently examines the relevant evidence, can identify errors or limitations, and has the authority and opportunity to change the outcome.

What are the privacy and fairness concerns?

Collection beyond what is needed

In its 6 November 2024 account of audits of recruitment AI developers and providers, the UK Information Commissioner’s Office (ICO) reported concerns that some audited tools gathered more information than necessary. The ICO also found examples of candidate information being kept indefinitely in databases without candidates’ knowledge. These are findings about audited providers, not evidence that every tool collects too much or retains data indefinitely. The ICO said providers accepted or partially accepted its recommendations, and follow-up confirmed recommended actions were implemented. Read the ICO’s audit account.

Inferences and proxy signals

An inferred attribute or proxy can be wrong, and using it in a hiring assessment can create privacy and discrimination risks. A score is not objective merely because software produced it: its significance depends on the data, criteria, and method behind it. Ask what the system infers, whether those inferences affect advancement, and how the employer checks for inaccurate or unfair results.

Decision-making and oversight

In the UK, government guidance says employers should consider whether an AI-based recruitment decision falls under Article 22 of the UK GDPR and whether a data protection impact assessment is required. The ICO’s later Recruitment rewired report says many employers using automated recruitment are likely relying on solely automated decisions with legal or similarly significant effects. It calls for clear candidate notice, consistent meaningful human involvement where claimed, and stronger fairness and bias monitoring. The applicable analysis depends on the specific decision and context. UK government guidance and the ICO’s Recruitment rewired report provide further detail.

For the EU, the AI Act Service Desk describes tools that evaluate candidates or materially influence ranking and shortlisting as a high-risk recruitment use case. It also gives examples of limited procedural functions that may be excepted; not every HR tool is automatically high-risk. The cited legislation is Regulation (EU) 2024/1689. Check the current official text and applicability dates for the particular system and use. EU AI Act Service Desk: Annex III.

Canadian federal public-service guidance offers a transparency benchmark in that context: explain the AI’s role, assessment criteria and data, each candidate’s output or feedback, and how decision-makers used the output. It also calls for bias mitigation and notice about assessment methods and accommodation procedures. This guidance is for the Canadian federal public service, not a universal rule for Canadian employers. Canadian federal public-service guidance.

How can a candidate find out what is happening?

Read the employer’s privacy notice and any information about the assessment method. If it does not answer your questions, ask the recruiter or employer directly; what rights and remedies apply depends on the tool, employer, and jurisdiction.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.
  • What information is collected, and what information is inferred?
  • Where did the information come from? Does the tool use CVs, online profiles, background records, or information from another source?
  • Does it analyze video, voice, facial features, or other signals?
  • What criteria does it apply, and does its output rank, filter, or reject applications?
  • Does a person review the result consistently, and can that person change the outcome?
  • How long is information retained, who can access it, and how can you correct an error or challenge a decision?
  • What assessment methods are used, and how can you request an accommodation?

Do not assume that a recording, online search, or particular inference is part of a process unless the employer confirms it. Likewise, a statement that a recruiter reviews results does not explain how much influence the system has or what the reviewer can do.

What should employers ask before buying or using a tool?

Employers should assess the actual configuration and use, not rely on a vendor’s general description. The ICO’s audits and UK recruitment guidance support due diligence on necessity, fairness, transparency, and assurance. Ask the vendor for documentation and verify how the system will operate in your hiring process.

  • Data map: what data is collected, its source, what is inferred, and which parties can access it.
  • Purpose and legal basis: why each category is necessary for the stated hiring purpose and what lawful basis is documented.
  • Retention and secondary use: a retention schedule, deletion process, and clear account of any vendor reuse or other secondary use.
  • System evidence: model and validation documentation, known limitations, and bias testing relevant to the intended role and population.
  • Accessibility: available accommodations, how candidates request them, and how alternative assessment routes are handled.
  • Meaningful oversight: who reviews outputs, what evidence they consider, whether they can override a result, and how consistent review is monitored.
  • Candidate communication: notices that explain the AI’s role, data and criteria, effect on decisions, retention, and routes to raise an error or concern.
  • Vendor chain: subprocessors, access arrangements, and responsibilities for responding to candidate requests or incidents.

Document how the tool is actually used, including whether a nominally administrative output in practice shapes selection. Compare systems on their data sources and inferences, influence on advancement, human review, candidate challenge routes, retention and vendor reuse, and the jurisdiction-specific safeguards that apply.

What is known about the scale of collection?

There is no representative universal figure for how many data fields recruitment AI tools collect, and the cited sources do not establish a standard retention period. The ICO reported making almost 300 recommendations after consensual audits of recruitment AI developers and providers; that number describes recommendations, not a market-wide count of data fields or a claim that every provider had the same problems. The ICO’s Director of Assurance, Ian Hulme, said: “AI can bring real benefits to the hiring process, but it also introduces new risks that may cause harm to jobseekers if it is not used lawfully and fairly.” ICO announcement, 2024.
