Candidate Experience Metrics
The KPIs your hiring system should track to keep candidates engaged, shorten Time to Fill, and protect Cost per Hire.
Why candidate experience is a recruitment ROI lever
Every drop-out resets a stage of the funnel — sourcing time, screening time, recruiter hours, and hiring-manager time. The math is brutal: a 20% drop-off after the technical interview can double your effective Cost per Hire because every two interviews only produce one viable offer. Candidate experience metrics are the early-warning system that catches this before it shows up in TTF and CPH dashboards.
Modern hiring systems should expose these metrics natively, alongside the financial KPIs you already track in the Cost per Hire calculator and the Time to Fill calculator.
The 6 metrics every hiring system should track
Candidate NPS (cNPS)
% Promoters − % Detractors
A single number that summarizes perception across the whole funnel. Benchmarks: >30 is good, >50 is excellent.
Stage drop-off rate
1 − (candidates entering stage N+1 ÷ stage N)
Pinpoints where your funnel leaks. Spikes after an assessment or interview round signal friction worth fixing.
Time to respond
Avg hours from candidate action → recruiter reply
Under 24h keeps top candidates engaged. Over 72h doubles the chance they accept a competing offer.
Interview-to-offer ratio
Offers extended ÷ interviews conducted
Low ratios mean you're interviewing the wrong shortlist — a screening or sourcing problem masquerading as a hiring problem.
Offer acceptance rate
Offers accepted ÷ offers extended
Below 80% usually points at salary, candidate experience late in the funnel, or slow decision-making.
Feedback completion rate
Candidates who got structured feedback ÷ rejected candidates
Strongly correlated with future-applicant rate and Glassdoor sentiment — your employer brand multiplier.
How to instrument them
- Trigger a 2-question survey after every stage transition (apply, interview, decision).
- Tag every candidate event with stage, recruiter, and source for cohort analysis.
- Set thresholds: NPS < 20, drop-off > 30%, time-to-respond > 48h → alert.
- Review monthly per role and per recruiter — averages across the whole company hide the problem cells.
- Tie each alert to one funnel fix: shorter form, async interview, faster feedback.
Connecting candidate experience to revenue
For a 50-hire/year team, lifting offer acceptance from 70% to 85% removes ~10 redundant funnels — typically $40–80k of recruiter time and ad spend. That's the ROI argument for candidate experience: it shows up in CPH, TTF, and revenue-per-hire, not just a Glassdoor star rating.
