Can one example answer any question?

Picture it. You prepared a story about clearing a backlog against a deadline. You know it almost word for word. Then the panel asks: “Tell me about a time you persuaded someone who disagreed with you.” Your story does have a persuading moment in it, but it's buried in the middle, and your script starts somewhere else. So you start rewriting while they wait.

The panic comes from the rewriting, not from a weak example. Your experience is fine. What's missing is a way into it from a different door. A script has one door. A set of blocks has several.

This happens a lot because panels don't read from a fixed list of questions. They write their own, based on the behaviour descriptions for the grade, and they often add a follow-up that pulls you somewhere you didn't plan. You can't predict the exact wording. You can prepare material that bends to it.

Civil Service jobs are assessed with Success Profiles, the framework every department uses for recruitment. It can test five things: behaviours, strengths, ability, experience and technical skills. The job advert tells you which ones your job uses and at which stage. Most interviews test behaviours: nine named ways of working, such as Communicating and Influencing, Making Effective Decisions, Delivering at Pace and Seeing the Big Picture.

Each behaviour comes with a list of statements that describe what good looks like at your grade. Grades run from Administrative Assistant (AA) and Administrative Officer (AO), through Executive Officer (EO), Higher Executive Officer (HEO) and Senior Executive Officer (SEO), up to Grade 7 and Grade 6. A question for an SEO expects bigger scope and more people involved than the same question for an AO.

For each behaviour, the panel listens to your answer and gives it a score. Many departments score each answer out of 7, and 4 is the usual pass mark, but check your candidate pack because it varies. They score what you did, so the action part of your answer carries most of the weight. That's why blocks work: each action block is evidence for a different behaviour.

You'll see the STAR method mentioned everywhere: Situation, Task, Action, Result. Some guides say STARR, which adds a second R for Reflection, meaning what you learned or would do differently. The block method on this page is STARR with the Action split into separate pieces you can move around.

Take one real story and break it into parts. The situation is one sentence. The task is one sentence. Then write two or three separate actions, each one a different thing you did, and tag each with the behaviour it shows. Finish with the result, with a number if you have one, and one line on what you'd do differently.

Here is one example, cut up. It's a made-up story written for this guide, not a real person. Use your own, from any job, volunteering, caring or study.

Look at what each action block does. Action A is about getting the facts before deciding. Action B is about bringing someone round who didn't agree. Action C is about keeping the work moving when people were off. Each one is a small complete story: what you did, why, and how. That independence is what lets you lead with any of them.

Write your blocks as short notes in your own words, not full sentences to memorise. If an action only fits a behaviour weakly, leave the tag off. Two strong blocks are better than three thin ones.

Here is the same example answering four questions the panel might ask. The facts are identical every time. What changes is which block you open with, and which block gets most of your time. The first line is the hardest part to find under pressure, so each one below gives you a line to fill in and the worked version.

Once you've chosen the lead block, the order is always the same. That helps more than it sounds: you make one decision, then the shape carries you.

The situation, in one sentence. About 15 seconds: where you were, what was happening, and the deadline if there was one. Don't linger here. Then the matching action, which gets most of your time, about a minute and a half. Say “I”, not “we”. Say what you did, why you chose to do it that way, and how.

The other actions get one line each, about 20 seconds in total, or you can skip them. Then the result, with the number, about 15 seconds. Finish with what you learned, in one line, about 10 seconds.

These timings are a rough guide and add up to about two and a half minutes. Panels differ. Some stop you and ask follow-up questions, some let you talk. Watch how they react to your first answer and adjust the rest.

Most people practise by saying each answer from start to finish. That trains the telling, which you already know. The part that causes the panic is the choosing, so drill that on its own.

Ask a friend or mentor to read out questions from your behaviours list in a random order. For each one you get 10 seconds to say only which example and which block you'll lead with. Then give just the first line out loud, not the whole answer.

Do 10 rounds. When picking the block feels instant, move on to full answers. If there's nobody to practise with, write the questions on cards, shuffle them, and do the same thing on your own, out loud.

Even with blocks, your mind can go blank. That's normal, and you can recover from it. Three things help.

Ask for a moment. Say: “Can I take a moment to think about that?” Panels hear this all the time. A short pause looks considered. A rushed answer to the wrong question costs you more.

Repeat the question back. Say: “So, a time I persuaded someone who disagreed…” It buys you a few seconds, and saying the key word out loud often tells you which block to use.

Keep a block list, if notes are allowed. Ask at the start of the interview whether you can refer to notes. If you can, have one line per example: its name and its A, B and C tags. Just the words, not scripts. Reading a script out sounds like reading.

If you start an answer and realise it's the wrong block, it's fine to say so: “Actually, a better example of that is…” and switch. That's better than finishing an answer that doesn't fit the question.

Tonight, take your strongest story and cut it up. Write the situation in one sentence, list every separate thing you did, then the result and what you'd change. Tag each action with a behaviour from your advert.

This week, do the same for two or three more stories, until every behaviour in your advert has at least one block that fits it. Then run the 10-round drill. Last, say full answers out loud. Plum's AI interview panel asks the questions in different wordings, follows up like a real panel, and tells you how each answer landed.
