Start with the advertised behaviour and grade
Prepare for a Civil Service behaviours interview by matching real examples to the behaviours and level described in the vacancy. Read the current Cabinet Office definitions for the relevant grade. A generic story about teamwork can leave the assessed behaviour unexplained.
This guide helps you organise evidence. It does not predict questions, give official scores or promise a successful application. If the vacancy also assesses strengths, prepare those through reflection using the separate strengths guide rather than applying the same script to both.
Turn the advert into an evidence map
Choose one advertised behaviour and one project you personally contributed to. Write down the decision, the information available, the alternative you considered and the outcome you can honestly describe. Distinguish your own action from what the team did.
Our fictional exercise uses a community workshop whose registration instructions confused attendees. You helped decide whether to rewrite the entire guide or change the two steps causing most questions. Explain what evidence supported your choice and how you checked whether the change helped.
| Evidence field | Example note |
|---|---|
| Situation | Attendees misunderstood registration instructions. |
| Decision | Fix the two confusing steps before rewriting the full guide. |
| Evidence | Repeated questions and a review with the event organiser. |
| Personal contribution | Drafted the changes and asked another volunteer to test them. |
| Outcome and learning | Describe observed feedback; do not invent a reduction percentage. |
Explain the decision before the outcome
A useful fictional answer describes why the smaller change was chosen: 'We had limited time before the event. I reviewed the questions volunteers had received and found two repeated points of confusion. I proposed changing those first and asked someone unfamiliar with the process to try the instructions.' The reasoning is visible before the result.
Then explain the outcome you know. If nobody measured time saved, say what was observed and what remained uncertain. Close with a lesson about testing instructions earlier. Replace the exercise with your experience when applying; fictional volunteer work must never become a claimed achievement.
Follow-up questions to test your reasoning
- What other option did you consider?
- What information was missing when you decided?
- Which action was yours rather than the team's?
Ask a practice partner to challenge vague verbs such as 'managed' and 'supported'. Revise the answer until you can identify a concrete action and its reason. Use the official grade-specific descriptors to check relevance, not an unofficial internet scoring formula.
Test one behaviour at a time
Keep an evidence bank rather than one long universal answer. A project can illustrate different behaviours only when the action and reasoning fit each question. Prepare an alternative example so you can adapt when a follow-up makes the first one less suitable.
This is an original Cluegent practice exercise. Its scenario, example wording and suggested timings are illustrative, not an employer's assessment or scoring system. Use genuine experience in a real interview.
For optional preparation, paste the exercise into Cluegent as a typed prompt and ask for one follow-up at a time. Review the reasoning before adopting suggested wording. Redact personal and employer-confidential information. Try Cluegent on Windows or macOS; check the current trial and paid terms before downloading. Follow the employer's rules during an actual assessment.

Where Cluegent helps
Cluegent supports permitted live workflows with transcript context, typed prompts, screenshot-aware answers, resume context, custom response behavior, quick action buttons, and a private desktop overlay. It is most useful when you already understand the subject and need help staying structured under pressure.
Frequently asked questions
Can I use the same example for different behaviours?
An example may support more than one behaviour, but explain the actions relevant to the question. Do not repeat an unchanged story regardless of what is asked.
Which grade should I prepare for?
Use the vacancy's grade and the corresponding official behaviour guidance. This worksheet is not a substitute for the advert.
