One preparation loop
From vacancy to a better second answer
Reading question lists can help you recognise themes. Rehearsal shows whether you can select evidence, explain your own decision and stop before the answer becomes a speech.
Build evidence
Record context, your choice, the result and what changed.
Say it aloud
Practise the full answer before the real conversation.
Inspect and repeat
Use visible checks, revise one weakness and answer again.
Useful feedback
No mystery score
The answer inspector reports only checks you can see: direct opening, specific situation, personal contribution, reasoning, supported result and reflection. It does not infer confidence, personality or employability.
“I chose the slower data check because…”
A decision becomes credible when the listener can follow the constraint, alternatives and evidence available at the time.
Decision language found
The phrase can be located in the answer. Whether the decision was good still requires human judgement and context.
