Most candidates prepare for an interview as if it were a conversation to survive. It is not a conversation. Behind the small talk sits a scoring sheet — and once you can see the sheet, everything about how to prepare changes.

The evidence is decades old and quietly decisive. Schmidt and Hunter's landmark analysis put the validity of structured interviews at .51 against .38 for the unstructured kind — the difference between an assessment and a chat. Organisations that hire well learned the lesson: same questions for every candidate, same order, and an anchored rating scale the panel scores against while you talk.

What the Sheet Actually Rewards

A scoring sheet does not reward charm, and it cannot read modesty as virtue. It rewards concrete answers with identifiable parts: the situation, what you did about it, what happened next. That is why the STAR format exists — it is not an arbitrary hoop, it is an answer-shaped object matched to the boxes the panel is marking.

It also explains the two mistakes that quietly sink candidates. Rambling loses marks because a long answer leaves the scorer hunting for the part that matches the scale. And vagueness loses because "we improved things" gives the sheet nothing to record. "I did this, it produced that" is the currency interviews run on — the research on self-presentation says candidates who own their actions outscore identical candidates who hide behind the team.

Skill, Not Genetics

The hopeful finding sits underneath all of this: interview performance is partly learnable, and learnable separately from job performance. That is an odd-sounding result with a deeply practical meaning — preparation buys real marks, not just calm. The nerves matter less than the rehearsal.

Rehearsal means drafting real examples, saying answers aloud until they come out level, and knowing which of the four question types is in front of you: behavioural, situational, CV-based, or strengths. Each has a different scoring logic, and the same story told the wrong way wastes the story.

A Week of Preparation, Done Properly

Our new Interview Skills that Work course builds the kit in seven daily emails: how panels actually score, the four question types, STAR done properly, honest self-promotion, turning nerves into fuel, the tricky questions and video interviews, and a rehearsal plan with follow-up. By the end you walk in with a story bank, drafted answers and a run-sheet — the scoring sheet's version of prepared.
