What should I do the night before a Civil Service interview?

You're here because you passed the sift, the stage where your written application was scored. The interview invite, and the candidate pack if your department sent one, tell you what happens next. Open them first and read them properly, even if you skimmed them when they arrived.

Look for four things. The format: Microsoft Teams, another video link, or in person, and the exact time. What's tested: the behaviours, strengths and experience listed for this job, which come from the Civil Service's Success Profiles framework. The scoring scale, if it's given. Anything you need to have ready, such as ID or documents, and whether notes are allowed.

Write the list of behaviours down. The advert usually names one of them as the lead behaviour; if it doesn't say, check the candidate pack. You'll see why that matters in the next step.

Each answer is scored on its own. Every behaviour, strength and technical question gets its own score from the panel. A behaviour question asks for a real example from your past (“Tell me about a time you…”). A strength question is quicker and asks what you enjoy or how you like to work.

Every behaviour has to pass. A 6 on one answer won't cover a 3 on another. This is the rule that catches people out: someone with one brilliant story and one thin one can fail on the thin one alone. That's why tonight is about your weakest answer, not polishing your best.

Ties often go to the lead behaviour. When two candidates end up level, the score on the lead behaviour is often what separates them. So your lead behaviour answer should be your strongest.

Passing every answer doesn't always mean an offer, because there may be fewer jobs than people who passed. If you pass but miss out, you may go on a reserve list, often for up to 12 months, and be offered a similar job later without interviewing again.

Take a sheet of paper. For each behaviour in the advert, lead behaviour first, write your example in one line: “The complaints backlog”, “The new starter who was struggling”. Then ask three questions of it, out loud if you can.

Did I say “I”, not “we”? The panel can only score what you did. “We sorted it out” gives them nothing to mark. Is the result clear? An answer that stops at what you did leaves them guessing whether it worked. What would I honestly score it, from 1 to 7? Be strict. If you'd need to explain it further for it to make sense, it's not a 5 yet.

Then go through the list below for every answer. Each line is something panels look for, and each one you can't tick is a quick fix.

If your interview tests strengths, give them five minutes too. They're scored, but there's no “right” answer to memorise. Practise a few quick-fire questions out loud, like “Do you prefer a plan or working it out as you go?”, and answer honestly and with energy. A flat, careful answer to a strengths question usually lands worse than a real one.

Circle any behaviour you scored 3 or below. If there's more than one, start with the lead behaviour, then the next lowest. Rework that example first: add what you did, and how it turned out. Don't swap to a new story tonight unless the old one really doesn't fit the behaviour.

Most weak answers are weak in the same way: a long set-up, a short “we sorted it out”, and no ending. Here's an example story, made up for this guide, before and after.

Before: “We had a big complaints backlog and my manager wanted it cleared. We all worked really hard and got it done before the review.”

After: “Our backlog hit 340 cases and I was asked to clear it in 8 weeks. I pulled the case data and found most were the same 3 issues, so I sorted them into quick fixes and complex cases. I set a weekly target and ran a 10-minute check-in each day. The backlog was down to 45 in 7 weeks. Next time I'd bring the other team in on day one.”

Same story. The second version says what “I” did, step by step, ends on a result with a number, and adds what you'd do differently. Write the new version down, then say it out loud twice. That's enough.

Once your weakest answer is fixed, put the examples away. Practising late into the night tends to make answers sound rehearsed and leaves you tired. Spend ten minutes on the practical things instead, so the morning has nothing in it to worry about.

Tonight: read the invite and pack, score each answer from 1 to 7, fix the lowest one, tick the list above, and go to bed. That's the whole job.

In the morning: reread the advert once, so the job's own words are fresh. Say your lead behaviour answer and your reworked answer out loud one time each. Then leave them alone.

An hour before: join early if it's online, or arrive early if it's in person. Have water nearby. When the panel says hello, answer warmly and briefly; the scored questions come a few minutes later.
