The term appears in most recruiter job descriptions and recruitment software products, yet its definition is not always clear. Here is what a talent pool is, what sets it apart from a plain CV database, and how to run it so that it produces hires. The short definition is also in our recruitment glossary.

A talent pool, also called a candidate pool, is the set of profiles a company or recruitment agency keeps in order to contact them again for future roles. It includes unsuccessful candidates judged worth keeping, speculative applications received with no open role, former interns, apprentices or temporary workers, and people approached through sourcing who were not available at the time. In its 2017 study on recruitment software, Apec describes it as applications that did not lead to a hire and that the company keeps for future recruitment, which lets it build "its own internal CV database".

The talent pool is one sourcing channel among others. In Apec’s 2018 Sourcing cadres survey, 37% of recruiters had drawn on it for their most recent executive hire in 2017, rising to 43% in companies with 1,000 or more employees. Apec added that a pool must be up to date to be relevant, which takes technical, financial and human resources.

The two terms do not always mean the same thing from one team to the next, so it is worth settling the definition before discussing figures.

  • Internal talent pool. Strictly speaking, current employees who can be offered an internal move. In many teams, the term also covers everything the organisation holds itself, as opposed to databases it rents.
  • External talent pool. People outside the organisation with whom there has already been contact, whether past candidates, speculative applicants or people approached through sourcing.
  • Job site CV databases. Databases owned by a third party that the recruiter accesses through a subscription. The recruiter holds no information of its own about the person there, neither interview nor assessment.

A talent pool’s value lies in that information of its own. A profile you have already met, whose verified skills, salary expectations and availability you know, can be requalified in one phone call. A CV found in an external database means starting over.

A talent pool fills up from four main sources.

  1. Unsuccessful candidates at the end of a process, especially finalists. These are the best documented profiles, since they have been through one or more interviews.
  2. Speculative applications. According to Apec’s 2026 executive recruitment practices barometer, 75% of companies with 250 or more employees drew on them for at least one executive hire in 2025, five points more than in 2024.
  3. Former interns, apprentices and temporary workers, already known to operational teams.
  4. People approached through direct sourcing or met at a job fair, who were not available or not interested at the time.

From the start, every profile goes in with its source, its date and how the person was informed, otherwise it will be impossible to work out its expiry date later.

A talent pool is judged at the moment you search it. Most pools are full but unusable, because the useful information sits in a free-text comment or in the memory of the recruiter who ran the interview. We cover this in our article on the dormant talent pool.

For a profile to surface at the right moment, its record needs a few fields filled in consistently.

  • Target role and job family, using a shared reference list rather than a free-text title.
  • Skills verified in interview, kept separate from those merely listed on the CV.
  • Location and mobility, accepted working arrangements and salary expectations.
  • Availability or notice period, with the date the information was given.
  • The latest interview assessment, written with facts (what the candidate said or showed) rather than an adjective.
  • The reason they were not hired, which tells you whether the profile was too junior, too expensive, unavailable or simply beaten by another candidate.
  • Date of last contact and legal basis, which set the retention deadline.

Tags help as long as you keep few of them and define each one. A list of thirty tags created along the way by each recruiter ends up sorting nothing. A handful of closed tags (job family, level, status in the pool) and a structured interview report that people will actually reread work better.

Keeping a candidate in order to offer them another role is a separate processing activity from the recruitment they applied for. It therefore needs a legal basis, clear information and a retention period.

  • Legal basis. For an unsuccessful candidate, the CNIL recruitment guide recommends obtaining their consent. Legitimate interest remains possible if the candidate is expressly informed and can object easily. For a speculative application, the guide considers it possible to treat sending the CV as agreement to its retention.
  • Information. Article 13 of the GDPR requires stating the purpose and the retention period at the time of collection.
  • Retention period. The CNIL recommends keeping a profile no longer than 2 years from the last contact, and considers five years excessive in principle for feeding a talent pool.

The detailed cases, with ready-to-use notice wording, are in our article on keeping a candidate in your talent pool. Deadlines and their starting points are explained in the article on candidate data retention periods, and our retention period calculator gives the dates for a specific case.

A talent pool that is only opened when a role comes up degrades quickly, because people’s situations change. A candidate who was unavailable eight months ago may be looking today, and another may have accepted a job last week.

Three habits are enough to keep it alive. First, check the pool before advertising any role, setting aside fixed time for it as soon as the role opens. Second, contact the best profiles again at regular intervals, with a personal message that refers to your previous exchange rather than a newsletter. Third, update the record and the date of last contact after every exchange, since the CNIL counts its recommended retention period from that date.

Reactivating a pool that has gone dormant follows a step-by-step method, from the initial measurement to tracking results, which we set out in reactivating a talent pool.

Two metrics are enough to tell whether the pool produces anything.

  • The share of roles filled from the pool, meaning by a candidate who was already in it before the role opened. Apec has published an old but telling benchmark. In its 2018 survey, when recruiters used their talent pool, it led them to the candidate finally hired in 6% of cases in 2017. In a 2017 study on recruitment software, more than one recruiter in two who had used their software reported drawing on the pool, yet the pool was the source of only 3% of hires made with software. Apec suggested the limited shelf life of applications as a possible explanation.
  • Time to hire for roles filled from the pool, compared with other roles. For reference, Apec reports that the most recent executive hire took 12 weeks on average in 2025, a delay that rose from 9 to 12 weeks between 2020 and 2022 and has held steady for the past two years.

Two health indicators complete the picture, namely the share of records whose last contact is less than 2 years old and the share of records that carry a usable assessment.

  • Keeping everything by default. A pool that takes in every CV received becomes unreadable and goes beyond the scope set by the CNIL, which covers only candidates whose profile interests the employer.
  • Forgetting the date of last contact. Without it, neither purging nor prioritising is possible.
  • Leaving the assessment in the recruiter’s head. When that recruiter leaves the team, the pool loses most of its value.
  • Multiplying copies. Spreadsheet exports and mailboxes form parallel pools that no purge reaches.
  • Mass messaging without personalisation. A generic message sent to the whole pool usually gets few replies and prompts candidates to ask to be removed.

A CV database is a stock of CVs, often one belonging to a job site that the recruiter pays to access. A talent pool gathers people the organisation has already been in contact with and about whom it holds its own information, such as an interview, an assessment or an availability date. In its guidance, the CNIL uses the term CV database for an employer’s or agency’s own internal pool as well.

The CNIL recommends no more than 2 years from the last contact with the candidate. This period is a recommendation rather than a legal requirement, and departing from it means being able to justify your choice. At expiry, you delete the profile or ask the candidate for renewed agreement. The CNIL considers keeping a profile for five years in order to contact it again excessive in principle.

Yes. Article 13 of the GDPR requires informing the person at the time of collection, in particular of the purpose and the retention period. For an unsuccessful candidate, the CNIL recommends obtaining their consent, or failing that informing them clearly and letting them object easily.

For a few dozen profiles, yes, provided it records the date of last contact and the legal basis. Beyond that, a spreadsheet multiplies copies outside the recruitment software, makes purging difficult and cannot find a profile based on what was said in an interview.

Measure the share of roles filled by a candidate who was already in the pool before the role opened, and compare the time to hire for those roles with the others. If both figures stay flat after six months of effort, the problem often lies in the quality of the records rather than their number.
