Quality of hire measures how well new employees perform after joining — through ramp speed, manager performance ratings, retention at ninety or one hundred eighty days, and goal attainment — validating whether interview scores and screening methods actually predicted on-the-job success.
Recruiting metrics like time-to-fill and cost-per-hire measure process efficiency. Quality of hire measures outcome effectiveness — did we hire people who succeed? Without it, teams optimise speed while regrettable turnover silently erodes the savings.
Evidence-based hiring programmes link interview scores to post-hire metrics: do candidates who scored high on the structured behavioural screen receive stronger manager reviews at six months? If not, the rubric or competency model needs revision — not louder insistence that interviewers 'trust the process.'
Quality measurement is noisy. Role changes, manager variance, and onboarding quality all affect early performance. Cohort comparisons — hires from the same requisition batch — reduce some noise versus comparing across unrelated roles.
Predictive validity research motivates structured interviewing, but local quality-of-hire tracking is how your organisation learns whether your telecaller rubric predicts call conversion or merely fluency. Campus programmes should compare fresher cohorts hired via async AI screen versus legacy manual screen.
Quality metrics also reveal interviewer bias patterns when certain interviewers' hires underperform despite high interview scores — suggesting lenient or irrelevant scoring. Audit sampling of scorecards complements aggregate quality dashboards.
Earliest meaningful signals often appear at 90 days for operational roles; six to twelve months for complex knowledge roles. Define windows per role family.
Related but different. Predictive validity is the statistical correlation between assessment and performance. Quality of hire is the operational outcome you track to see if validity holds locally.
Ask for criterion-related validity studies and offer to run your own score-to-performance analysis. Marketing claims without data are not evidence.
