Prepare for domain-technical interview rounds — the rounds where the user will be tested on what they claim to know (clinical development, regulatory strategy, asset evaluation, trial design). Reference when preparing for a clinical depth interview, a VC diligence round, a CMO scientific scrutiny round, or any conversation where the interviewer will probe technical mastery. The senior interviewer is testing reasoning under uncertainty, not encyclopedic recall.

From the source SKILL.md

Domain-technical interview rounds are where the most ambitious clinical-physician candidates make their biggest mistakes. The temptation is to prepare across breadth — refresh every therapeutic area, every regulatory pathway, every trial design archetype. The senior interviewer is testing something else entirely: can you reason under uncertainty, can you name what you don't know, can you build a credible argument from incomplete information? The right preparation goes deep on the user's actual expertise and rehearses the thinking pattern, not the encyclopedia.
