Recruiting Metrics and KPIs: The 10 That Matter
The recruiting metrics that matter form a funnel story: pipeline coverage and source effectiveness at the top, conversion and interview-to-hire ratio in the middle, and time to fill, cost per hire, offer-acceptance, and quality of hire at the bottom. Track those ten consistently and you can diagnose any hiring problem; track only time-to-fill - the most common habit - and you'll optimize speed while quality and cost drift.
The 10, with benchmarks
- Time to fill: req opened → offer accepted. Benchmark ~36-44 days; AI-interview pipelines routinely run under 15.
- Time to hire: candidate applied → accepted; measures process speed candidates actually feel.
- Cost per hire: all-in spend ÷ hires (include interviewer hours - most teams don't). SHRM average ≈ $4,700.
- Interview-to-hire ratio: candidates interviewed per hire. 4-6:1 is healthy with good screening; above 10:1 your top-of-funnel signal is weak.
- Pipeline conversion by stage: where candidates die tells you which stage is broken.
- Offer acceptance rate: below ~85% points at speed, comp, or experience problems.
- Source effectiveness: hires (and quality) per source, not applications per source.
- Candidate drop-off: scheduling friction is the usual killer - one team cut drop-off 58% → 12% with 24/7 AI interviews.
- Quality of hire: performance + retention + ramp - the metric the rest exist to serve.
- Hiring-manager satisfaction: cheap to collect at 90 days, brutally honest.
Why AI-run pipelines report cleaner metrics
Manual pipelines measure what recruiters remember to log. When sourcing, outreach, interviews, and scoring run through one platform, every stage stamps its own data: true conversion rates, real interview-to-hire ratios, and per-source quality - with interview evidence attached. The Cognitive's analytics report these per role out of the box.
Frequently Asked Questions
What is a good interview to hire ratio?
Around 4-6 interviews per hire when screening is working. Ratios above 10:1 mean weak top-of-funnel filtering; ratios near 2:1 may mean you're filtering too hard before interviews. AI interviewing shifts the math: interviewing everyone raises the raw ratio but replaces cheap noise with evidence - what matters is final-round pass rate, which typically doubles.
What's the difference between time to fill and time to hire?
Time to fill starts when the req opens (business view); time to hire starts when the eventual hire applied or was sourced (candidate view). Track both - a long fill with short hire means sourcing started late; the reverse means your process drags.
