Time-to-fill is one of the metrics every TA team tracks. It is reported as a recruiting metric — a measure of how efficient the sourcing pipeline, the interview process, and the hiring decision are. Recruiting tools optimise for it. Vendors benchmark on it. Quarterly TA reviews report it.
It is a useful number. It is also rarely the right diagnosis when it moves the wrong way. A recruiting funnel that gets materially slower for a specific role rarely got slower because the funnel changed. The candidates didn't suddenly become harder to find; the conversion rate didn't suddenly drop. What changed, in most cases, is that the band's external reference moved and the offer rate stopped winning.
Three diagnoses for the same number
A role that historically filled in 45 days now takes 90. The TA team can read this in three different ways:
The first two are visible at the top and middle of the funnel. The third is visible at the bottom — at the offer stage. Most TA teams measure the first two and miss the third.
What time-to-fill is actually measuring
The time from role opening to accepted offer is the sum of three durations: sourcing time, screening time, and offer-acceptance time. The third is where the compensation signal lives.
If candidates reach the offer stage at normal rates but the offer is rejected or countered more frequently, time-to-fill increases without anything visibly wrong upstream. The funnel is "working" — candidates are sourced, screened, interviewed — but the close rate at offer time has dropped.
This pattern is unmistakable in the data once isolated. Three indicators surface it:
- Offer acceptance rate. Same number of candidates reaching offer stage, fewer accepting. The candidates haven't changed; the offer has stopped matching what they can find elsewhere.
- Counter-offer frequency. Candidates who accept after a counter — meaning the original offer was below their other options — are negotiating up. Frequency rising is a signal the original offer is no longer at-market.
- Cycle time at offer stage. The duration from offer extended to accepted/declined. Lengthening means candidates are weighing alternatives more carefully — usually because the alternatives became more competitive.
The PTD angle
Under Article 5, the indicative pay range is disclosed before the interview. The candidate self-selects whether to enter the process based on the disclosed range. If they enter, they are signalling the range is acceptable.
If time-to-fill subsequently drifts upward despite this self-selection, one of two things is happening: either the disclosed range is being overshot during negotiation (which surfaces a documentation gap — the published range stopped matching the actual offer trajectory), or the band itself has drifted below the current market between the publication of the range and the offer stage.
Either way, the band needs updating. The disclosed range and the actual offer practice should match; if they don't, both the recruiting outcome and the Article 5 record diverge.
Time-to-fill is not a clean signal in isolation — many factors influence it. The point is not to use it as the primary diagnostic. The point is to add the compensation lens when the metric moves materially. Sourcing and process explanations are useful when they apply; they apply less often than they are invoked.
What to do with the signal
When time-to-fill rises for a specific role and the upstream funnel metrics look normal:
- Pull offer-stage diagnostics. Acceptance rate, decline reasons, counter-offer frequency over the last 6 months for that role. Compare to baseline.
- Triangulate market. Recent decline-reason narratives (compensation cited?), competing-offer data the recruiter has on file, public job posts for comparable roles in the geography.
- Recalibrate the band. If the market reference has moved, the band moves with it. Update the documented range; the disclosed Article 5 range updates automatically because they reference the same source.
- Communicate the recalibration internally. Existing employees in the same band benefit from the recalibration; the per-category metrics in the next reporting cycle will reflect it. The directive's framework rewards proactive recalibration over reactive counter-offers.
The funnel didn't get slower. The market moved. Time-to-fill is the messenger.
Where the diagnostic starts
Reading time-to-fill as a compensation signal requires the band to be documented in the first place. Without a defined band, there is no "below market" to be below. HireGapCheck™ produces the cohort comparison view at the point of offer — the same view that surfaces whether the proposed offer is at, above, or below where the cohort currently sits, and whether time-to-fill drift is consistent with band-level recalibration.
Read time-to-fill at the offer stage, not at the funnel top.
HireGapCheck™ produces the offer-vs-cohort view that surfaces band drift before it costs you another 45 days. Three minutes per simulation.
