Hiring Funnel

Most engineering managers treat hiring as a single monolithic activity. Larson’s hiring funnel breaks it into four distinct stages — Identify, Motivate, Evaluate, Close — each with its own success criteria and failure modes. The key insight: a hiring process isn’t failing; a specific stage is leaking, and the fix depends on which one.

The Four Stages

1. Identify — finding people to enter the top of the funnel

  • Feeds from Three-Candidate-Sources: inbound applications, referrals, and sourced candidates
  • Success metric: relevant candidates per week entering the pipeline
  • Failure mode: insufficient volume (not enough sourcing activity) or poor precision (too many irrelevant candidates creating evaluation bottleneck)
  • Fix: invest in the underperforming candidate source for your role type; for senior/specialist roles, emphasize sourcing via Cold-Sourcing-Technique

2. Motivate — getting candidates interested enough to engage

  • Success metric: percentage of contacted candidates who agree to proceed
  • Failure mode: strong candidates identified but they decline to engage — employer brand is weak, job description is uncompelling, or initial outreach fails to convey the opportunity
  • Fix: rewrite job descriptions to focus on what’s interesting about the work; improve outreach messaging quality

3. Evaluate — assessing candidates against role criteria

  • Mechanisms: phone screens, technical assessments, onsite interviews, reference checks
  • Success metric: offer rate among candidates completing evaluation; also, where in the process candidates fail
  • Failure mode A: high rejection rates may mean evaluation is miscalibrated (too hard relative to actual role needs)
  • Failure mode B: wrong candidates reaching evaluation — a symptom of Identify failure, not Evaluate failure
  • Fix: audit evaluation criteria against role requirements; track rejection by stage to locate miscalibration

4. Close — converting offers into accepted offers

  • Success metric: offer acceptance rate
  • Failure mode: excellent evaluation, offer extended, candidate declines — usually a compensation mismatch, slow process allowing a competing offer to land first, or failure to maintain candidate engagement during evaluation
  • Fix: compress time-to-offer; ensure compensation is competitive; maintain candidate motivation throughout

Diagnostic Framework

The funnel is a diagnostic tool:

SymptomLikely Leaking Stage
Many identified, few engageMotivate
Engage but fail evaluation at high ratesEvaluate (miscalibrated) or Identify (wrong candidates)
Pass evaluation but decline offersClose
Too few candidates to start withIdentify

Beyond the Core Funnel

The four stages above address getting a candidate to join. A natural extension covers what happens after the offer is accepted: onboarding, ramping to impact, promotion readiness, and retention. This extended perspective treats long-term talent development as a continuation of the hiring funnel rather than a separate system.
