Follow-up questions to prepare for
After your initial answer, the panel may ask follow-up questions to probe deeper. Prepare for these:
- "What would you do differently if you faced that situation again?"
- "How did you ensure your approach was the right one?"
- "What was the most difficult part of that situation, and how did you handle it?"
- "How did you measure the success of your actions?"
- "What did you learn about yourself from that experience?"
Civil Service interviews typically use structured behavioural questioning. Each question is designed to assess one or more behaviours from the Success Profiles framework. The panel will score your answer against the level descriptors for the grade you are applying for.
How to structure your answer
- Situation (30 seconds): Set the scene briefly. One or two sentences.
- Task (15 seconds): What was your specific responsibility?
- Action (90 seconds): What did you do? Use "I" not "we". Be specific.
- Result (30 seconds): What was the outcome? Include a number if you can.
