A competency-based interview asks for evidence, not opinion: every question is a request for a specific past situation that demonstrates a defined skill, scored against criteria written before you walked in. UK employers use the format precisely because it is comparable — each candidate is measured against the same descriptors — which means you can prepare for it more directly than for any other interview style.
This hub covers the format end to end: how scoring actually works, the competency families that recur across employers, and a question bank with four fully marked model answers from families our STAR method guide doesn't already cover — adaptability, integrity, planning and customer focus. For the answer structure itself, the STAR guide is the companion page; for the public-sector version, the civil service guide maps this format onto Success Profiles.
The preparation that pays is a story bank, not a script: six to eight real examples, each strong enough to flex across a family of questions. The question bank below is organised to help you build exactly that.

How the marking guidance works
Each model answer below is marked against the four criteria a live aurate session scores:

aurate is a practice tool. Marking guidance describes what strong practice answers show — it isn't an employability assessment.
Why it's asked: Adaptability is now among the most tested competencies in UK interviews. Panels score the speed and grace of your adjustment — and, at stronger levels, whether you helped others adapt rather than merely coping yourself.
Halfway through a system rollout I was coordinating, the supplier withdrew the version we had trained sixty staff on — their support deadline moved, and we had six weeks to switch to the newer version or run something unsupported.
I gave myself one afternoon to be annoyed, then treated it as a re-plan rather than a setback. I ran a gap analysis that evening: of our twelve training modules, seven were unchanged, three needed screenshots replacing, and two needed genuine redesign. That shrank the problem from 'retrain everyone' to 'redesign two modules' — and I communicated exactly that framing to the sixty staff, because the version they had heard was 'everything we learned is obsolete', and morale was becoming the bigger risk.
We converted the two modules into short floor-walking sessions in week one of go-live rather than classroom time before it, which people preferred anyway. Go-live happened inside the original window, the two redesigned areas generated the fewest support tickets of any module — attention follows redesign — and the gap-analysis habit became my standard first response to any imposed change: measure the delta before reacting to the drama.

Why it's asked: The integrity family, in its most common workplace form. Panels want the pressure acknowledged as real, the line held without theatre, and the relationship with the senior person intact afterwards — professional courage, not confrontation.
A director wanted our supplier-performance figures in a stakeholder pack two days before the data cut-off that made them reliable — the early version would have flattered one supplier because their worst week fell just outside the window. He knew the pack's date; he didn't know the cut-off detail, and 'just use what we have' was said in the tone of a decision already made.
I didn't relitigate it in the meeting. I sent him a three-line note within the hour: the early figures would overstate one supplier's performance, here is the specific week that changes the picture, and here are two options — publish with a dated caveat, or hold that single table for two days while the rest of the pack goes out on time. I made the recommendation explicit: hold the table. Making it easy to choose right mattered more than being right.
He took the two-day option without comment, and the pack went out with accurate figures. Nothing dramatic happened — which is the point. Six months later his office started asking us for 'the cut-off check' on data requests, which told me the note had changed a habit, not just a table.

A story bank only works out loud
Competency interviews are won by retrieval under pressure: the right story, structured, in two minutes, with follow-ups incoming. A live aurate session drills exactly that against your CV and target role, and marks every answer on the four criteria used above. Two free sessions. No credit card.
Try it freeWhy it's asked: The planning and organising family. Panels score the machinery — how you broke the work down, found the dependencies, built in slack — and what happened when the plan met reality, because every real plan does.
I organised the relocation of our 40-person office over a single weekend — the kind of project that is entirely logistics and entirely unforgiving, because Monday morning arrives whether you are ready or not.
I planned it backwards from Monday 8am. Working in reverse exposed the true dependencies: phones needed the network live, the network needed the comms room signed off, the comms room was the landlord's job and therefore my biggest risk — so I moved it to the front of the timeline and negotiated its completion a full week early, with a walkthrough test rather than a promise as the evidence. Everything movable got a numbered-zone system matching desks to crates, and I published one A4 page per team: your zone, your boxes, your Monday desk.
Two things still went wrong, as they do: a lift failed on Saturday morning, and one team's crates were double-numbered. The lift cost us ninety minutes against the four hours of slack I'd built into Saturday for exactly this category of surprise; the crate clash was resolved from the master list in twenty minutes. Monday 8am, 38 of 40 people worked normally; the last two were live by ten. The backwards plan and zone system were reused for the next office move after I'd left — by the colleague I'd walked through the method.

Why it's asked: The customer focus family — with a hidden edge. Panels want genuine user-centredness, but they also score judgement: did you bend the process safely and visibly, or create a precedent and a risk? The strongest answers help the user and improve the process.
A customer rang about an application rejected for a missing document — the third rejection in a cycle, because each rejection letter restarted a process that took her weeks. Listening properly, the real problem surfaced: she was a carer, the document needed a counter-signature from a professional she could only reach at specific times, and our fourteen-day deadline kept expiring in exactly that gap.
The standard response was another letter. Instead I checked what the process actually allowed rather than what we usually did — and found the deadline was our convention, not a legal requirement. I extended her deadline to thirty days on a documented discretion, noted the reason on her file so the next colleague would not undo it, and completed the rest of her checks by phone in the same call so the counter-signature was the only outstanding item.
Her application completed eleven days later, at the third attempt becoming the last. Then I did the part that made it competency evidence rather than a good deed: I wrote up the case pattern — carers hitting the fourteen-day wall — and the team lead agreed a flagged extension option for carer cases, which used the discretion we had always had. Four similar cases used it in the following quarter, none of which required anyone to be lucky enough to reach me.

Why it's asked: The teamwork family — the most common competency of all. Full worked treatment, including a marked model answer, is in our STAR method guide; the beat to protect here is the boundary between your contribution and the team’s.
Why it's asked: The drive-and-resilience family. Panels score where the time came from — re-scoping, sequencing, negotiation — rather than stamina. Our delivering at pace guide works this family in depth for public-sector interviews; the private-sector version scores identically.
Why it's asked: The analysis family. The differentiator is the loop: problem framed, evidence gathered proportionately, conclusion tested against someone who disagreed, decision taken. Candidates who only narrate the analysis miss the decision half of the marks.
Why it's asked: The influencing family — scored on method and respect rather than victory. Prepare one upward example and one peer example; panels often ask for whichever you did not lead with.
Why it's asked: The self-awareness family, and the question most often answered dishonestly — which panels know. A real miss, owned specifically, with the harm fixed and the system adjusted, scores; a strength in failure costume does not survive the follow-up.
Why it's asked: A meta-question that rewards preparation directly: it tests whether you've decoded the role's competency profile from the advert and can map your story bank onto it honestly — including naming the competency where your evidence is thinnest and what you're doing about it.
Questions that ask for a specific past example demonstrating a defined skill — usually opening with "tell me about a time" or "give an example of". Interviewers score your answer against written descriptors for each competency, which makes the format predictable: identify the competencies from the advert, and prepare evidence for each.
Each competency is rated separately against level descriptors, commonly on a numeric scale, and many employers require a minimum score per competency rather than a good average. This is why one unprepared competency can sink an otherwise strong interview — coverage across the advertised set beats brilliance on your favourites.
Six to eight real examples, each flexible across a family of questions, beat twenty rehearsed scripts. Choose stories with genuine substance — a decision, a conflict, a result — and practise re-angling each one, because the same project can evidence teamwork, planning or influence depending on which actions you foreground.
For experience-based competency questions, yes — it matches how assessors take notes and score. Keep Situation short, make the Action section carry your specific contribution, and end with a checkable Result. Our STAR method guide works the structure in detail with marked examples.
Closely related: the civil service assesses behaviours under Success Profiles, which are competencies with published definitions, often mixed with strengths questions. The scoring discipline is the same. If your interview is with a government department, our civil service guide maps this format onto the nine behaviours directly.
