Context

The team ran continuous hiring across customer support, voice, and back-office roles. Volume regularly exceeded what recruiters could review manually, and quality varied across regions and interviewers.

Challenge

  • Manual phone screens produced inconsistent communication evaluations across recruiters.
  • Recruiters could not keep up with applicant volume during ramp periods.
  • Operations leaders lacked clean attrition signal correlated with screening evidence.

Solution

  • Expert Hire ran structured async voice interviews scored on clarity, tone, comprehension, and role-fit.
  • Recruiters reviewed shortlists with evidence summaries instead of full transcripts.
  • Operations correlated post-hire attrition with screening signal to refine thresholds quarterly.

What this means

For BPO and high-volume hiring, AI interviews are most useful when they create reviewer-ready summaries and a feedback loop into post-hire performance.
