Time-to-fill is one of the most visible recruitment metrics. It tells leaders how long a vacancy takes to close, and it is useful for planning and spotting delays. But on its own it cannot tell you whether the right person was hired, whether the candidate joined, or whether the appointment delivered value to the business.
A recruitment process can improve its time-to-fill while creating more rework later. A role may be filled quickly but reopen after early attrition. An offer may be accepted but the candidate may not join. A shortlist may arrive on time but miss the capabilities the hiring manager actually needs.
The answer is not to abandon speed. It is to measure speed alongside quality and conversion.
Begin with a well-defined vacancy
Before tracking recruitment performance, make sure the role itself is clear. Recruiters and hiring managers should agree on outcomes, essential skills, location, compensation range, reporting relationships and realistic deal-breakers. A vague brief creates false activity: more CVs, more interviews and more changes of direction, without improving the chance of a good hire.
Record the date a requisition is approved and the date it is genuinely ready to source. This stops delays caused by incomplete approvals or changing requirements from being blamed entirely on recruiting.
Six recruitment metrics that give a fuller picture
1. Time-to-fill and stage-level delays
Track the overall cycle, but break it into stages: requisition approval, sourcing, shortlist, interview scheduling, feedback, offer approval and joining. Stage-level data shows whether delays sit with talent availability, slow feedback, multiple approval layers or an unrealistic brief.
2. Shortlist hit rate
If many submitted profiles are rejected, the problem may be search quality or role calibration. If few receive feedback at all, the process may be too slow, or the hiring manager may be applying criteria that were never agreed. Review a sample of rejected profiles rather than treating every rejection as a recruiter failure.
3. Interview-to-offer conversion
A very low conversion rate can point to inconsistent screening, weak interview alignment, or mismatched compensation and role expectations. It should trigger a joint review of evidence and selection criteria, not an automatic request for more CVs.
4. Offer acceptance and joining
Separate offers made, offers accepted and candidates who actually join. Analyse withdrawals by reason, role, location, notice period and time between offer and joining, to see whether the issue is compensation, engagement, delays, competing offers or concerns raised late.
5. Early retention
Measure whether new hires stay through agreed checkpoints, such as 30, 60 and 90 days. Review early exits with the hiring manager and, where possible, the employee. Separate avoidable mismatches from changes in business plans or other factors outside the recruiter’s control.
6. Quality of hire
Quality of hire has no single universal formula. Organisations can combine early performance, manager feedback, goal achievement, capability fit and retention, using measures suited to the role. What matters is agreeing the definition before results are reported, and applying it consistently.
Recruitment metric formulas
| Metric | Formula | What it tells you |
|---|---|---|
| Shortlist hit rate | Profiles shortlisted by the client ÷ total profiles shared × 100 | How well the search matches the brief |
| Selection hit rate | Offers made ÷ total profiles shared × 100 | How many shared profiles lead to an offer |
| Offer acceptance rate | Offers accepted ÷ offers made × 100 | How competitive and well-managed your offers are |
| Joining rate | Candidates who join ÷ offers accepted × 100 | How well candidates are engaged before joining |
| 90-day retention | Hires still employed at 90 days ÷ hires who joined × 100 | Whether the role and the person were matched well |
Use a balanced recruitment scorecard
A useful scorecard holds a small set of measures: time-to-fill, shortlist hit rate, interview-to-offer conversion, offer-to-joining conversion, early retention and hiring-manager feedback. Review results by role family, location, business unit and source where the data is reliable enough to compare.
Do not rank recruiters on one metric without considering how hard their vacancies are. A specialist leadership role and a high-volume frontline role have different talent markets and constraints, and targets should reflect that.
Turn reporting into action
A dashboard has value only when it leads to a decision. If joining conversion is weak, test candidate communication and offer processes. If time is lost in interview feedback, agree response standards with hiring managers. If early attrition is high in one team, examine job previews, supervision, induction and working conditions as well as recruitment.
Recruitment is a shared business process. Recruiters influence sourcing, assessment and candidate engagement; managers own role clarity, interview quality and the environment the new hire joins.
Frequently asked questions
What is quality of hire?
Quality of hire describes how much value a new employee adds, usually measured through early performance, manager feedback, goal achievement and retention. Agree the definition for each role family before you report it.
What is the difference between time-to-fill and time-to-hire?
Time-to-fill usually runs from requisition approval to offer acceptance; time-to-hire runs from when a candidate enters the process to acceptance. Whichever you use, define the start and end dates and keep them consistent.
How often should recruitment metrics be reviewed?
Monthly for active mandates, with a quarterly review of trends by role family, location and source.
The question that matters
The most meaningful question is not simply “How quickly did we fill the vacancy?” It is “Did we help the business bring in the right capability, at the right time, and create the conditions for that person to succeed?” At TNSL, every recruitment rate we publish comes with its formula, so clients can hold us to the same measure.
