Domain skills: can they actually do the job?
Cognition and personality predict potential; domain tests reality. How per-role, concept-tree-grounded domain questions measure the work itself — fairly across candidates.

A deep dive into one of the five pillars of a hire: domain skill — the pillar that tests the job itself.
Potential is not proof
A candidate can reason well and still not know how to reconcile a ledger, trace an incident, or write the query. Domain skill is the pillar that asks the one question the others cannot: can they do this work?
This is where the evidence is strongest. Work-sample and job-relevant skill tests are among the best-validated predictors of performance in the entire selection literature — they beat résumés, degrees and unstructured interviews by a wide margin, because they measure the thing itself rather than a proxy for it. The catch is fairness and consistency: a work sample is only as good as its coverage and its scoring, which is why generation has to be systematic rather than ad hoc.
Systematic, not sampled
Generated domain questions are grounded in concept trees so coverage is deliberate, and drawn from a three-tier bank that keeps content fresh per job.
