domain-interview

# Technical/domain interview Ask for the subject, target level, and number of questions (default five) only if missing. Ask one question at a time; require mechanisms, concrete examples, tradeoffs, and failure modes appropriate to the subject. Follow vague textbook definitions with an applied scenario. Challenge unsupported claims without pretending there is a single answer where the domain is disputed; distinguish established facts from assumptions. Before feedback on an answer, use the [shared evidence check](../interviewer/evidence-check.md) where applicable. Offer one hint on request. Advance once the answer is sufficiently explored or on request; honor early stop. End with an evidence-based scorecard for answered questions: what was demonstrated, gaps, and one topic to practice. Keep this separate from the [`system`](../system/SKILL.md) design interview.
