Most hiring problems aren't candidate problems — they're process problems. Here are the ten most common mistakes and the fix for each.

  1. No structured intake. Hiring without a clear target results in 50 interviews and zero offers. Start with a one-page role spec.
  2. Job descriptions written for compliance, not candidates. Lead with outcomes and impact, not bullet-point requirements.
  3. Single-source sourcing. Relying only on inbound or only on a recruiter creates blind spots. Run 3+ channels in parallel.
  4. Unstructured interviews. Same role, different questions, different interviewers — you're measuring noise, not signal.
  5. No interviewer training. Most hiring managers have never been formally taught to interview. Two hours of training pays back tenfold.
  6. Slow feedback loops. Top candidates have 3 offers. If your decision takes a week, you lose them.
  7. Reference checks as a formality. Done well, references uncover deal-breakers no interview will.
  8. Ignoring base rates. If 80% of candidates pass your screen, your screen is broken.
  9. No onboarding plan before offer accept. The first 30 days are made or broken before day one.
  10. Failing to debrief losses. When a candidate declines, the data is gold. Capture it.
