Key Performance Indicators (KPIs) are metrics that help you track the overall success of your recruitment process and gain insights on how you can improve effectiveness in key areas. Though specifics vary according to hiring goals, six common KPIs recruiters track may include quality of hire, time to interview, time to hire, interviews per hire, cost per hire, and retention rate. Tracking your metrics around these six areas will help you recognize which areas in your recruitment process are performing well and which could be adjusted so that you can snag top talent.
