The Definition of Time to Fill
Time to fill is the number of calendar days between a VP or C-suite role opening — defined as the date the search mandate is signed — and the date an offer is accepted by the selected candidate. It is the primary efficiency metric in executive search and a direct driver of cost of vacancy for the hiring company.
Time to fill should not be confused with time to start (the additional time between offer acceptance and the candidate's first day, which includes notice periods) or time to productivity (the time from start date to full contribution). All three matter, but time to fill is within the search firm's direct control.
What Drives Time to Fill
Intake quality
The single largest driver of time to fill is the quality of the role brief. A precise brief produces a precise shortlist. A vague brief produces iteration — multiple rounds of sourcing, presentation, and client feedback before the right candidate is identified. Each round adds weeks.
Sourcing depth
Firms that source primarily from active candidates and databases move faster initially but often stall when the best candidates are not active job seekers. Passive-first sourcing takes longer to initiate but produces better shortlists and shorter overall cycles.
Client responsiveness
Delayed feedback, rescheduled interviews, and decision committee bottlenecks add days to every stage. A search firm can control its side of the process — the client's responsiveness is equally important.
Offer construction
A well-structured offer — one that addresses the candidate's compensation priorities, equity expectations, and role scope — closes faster than one that requires multiple rounds of negotiation. Offer design is part of the search firm's job.
Time to Fill Benchmarks
"Time to fill is a lagging indicator of intake quality. A search that closes in 41 days was won in the intake conversation. A search that stalls at week 10 typically had a vague brief, a misaligned compensation structure, or a profile that was optimised for the wrong thing — all discoverable at intake."
Time to Fill vs. Time to Productivity
Time to fill ends when the offer is accepted. The candidate's notice period then begins — typically 2–4 weeks for mid-market VP hires, sometimes 3 months for senior leaders in certain industries. Time to productivity begins on the first day and depends heavily on onboarding quality. Companies that optimise for time to fill but neglect onboarding frequently see strong time-to-fill metrics and poor 90-day outcomes.
