Hire right, because the penalties for hiring wrong are huge

That starts with defining the role clearly — the actual values, abilities, and skills it demands — and then testing candidates directly against those specific requirements rather than against a general impression of “seems sharp” or “went to the right school.” Look for evidence of past behavior, not promises about future behavior; check references with pointed questions about how the person actually acted in hard moments, not vague impressions of whether they were “great to work with.”

The biggest danger in the whole process is wishful thinking. Once you've decided you want someone to work out — because the role is urgent, because you like them personally, because the search has already taken too long — you start interpreting ambiguous signals generously in their favor. The better discipline is the opposite: assume you might be wrong about this candidate, and go actively looking for the evidence that would disconfirm your favorable read, rather than settling for the evidence that confirms it.

Hiring well also requires honesty about fit, separate from raw talent. A person can be genuinely capable and still be the wrong match for a specific role or a specific culture, and pretending otherwise because they're impressive on paper only delays an inevitable, more painful reckoning. Making that call early — even when it's uncomfortable — is kinder to everyone involved than letting a known mismatch linger for months while it slowly does damage.

When hiring is done with this level of rigor, it protects the entire system downstream: fewer bad decisions get made, less time gets wasted managing mismatches, and the culture stays coherent. When it's done poorly, the organization pays a hidden tax on every decision that person touches, for as long as they're in the role.

Personality assessments can help here, because they surface how someone naturally thinks and behaves in a way an interview rarely does. And don't hire people just to fit the first job they'll do; hire people you'd want to share your life with, since good people will grow into many roles over time.
