Competency-based interview questions, and what is actually being scored
A competency interview asks you to describe things you have already done, on the theory that past behaviour predicts future behaviour better than opinions do. Every question is a variant of "tell me about a time when…", and the answer is marked against a list.
What the interviewer is holding
Not a blank pad. A scoring sheet, with the competency at the top and a short list of behaviours underneath it — "identifies the problem independently", "describes own contribution distinctly from the team", "states a measurable outcome". They tick what they hear and score it after you leave, usually one to five.
That one fact changes how you should answer, and it is why the advice to "be yourself and tell a good story" is wrong here. An answer that does not contain the behaviour cannot be given the mark, however engaging it was. Interviewers who liked you still cannot tick a box you did not give them.
It also explains the single most common failure, which is talking about what the group did. The sheet has your name on it.
Which competencies come up is not a mystery
Employers ask about the competencies they put in the advert. We counted which ones those are across 12,914 live UK graduate adverts on 5 November 2026, and the eight below are the ones worth preparing. The percentage is how often each is named.
Before an interview, read the advert again and underline the behaviours. In most cases the questions you get will be those, in that order. The full count is here.

The eight, and the questions used for each
Teamworknamed in 55.7% of adverts
They are listening for: Whether you can name what you personally did inside a group result. Almost every weak answer here says “we” for ninety seconds and never says “I”.
- Tell me about a time you worked as part of a team to achieve something.
- Describe a situation where a team member was not pulling their weight.
- Give an example of when you had to work with someone you found difficult.
Problem solvingnamed in 24% of adverts
They are listening for: The steps between the problem and the answer. People jump straight from “there was a problem” to “I solved it”, and the middle is the entire question.
- Tell me about a complex problem you solved.
- Describe a time you had to make a decision without all the information.
- Give an example of when your first approach did not work.
Communication skillsnamed in 28.6% of adverts
They are listening for: Evidence you changed how you explained something for the person in front of you, rather than that you talked a lot.
- Tell me about a time you explained something complicated to someone who did not know the subject.
- Describe a situation where you had to persuade someone to change their mind.
- Give an example of when you had to deliver bad news.
Initiativenamed in 19.2% of adverts
They are listening for: That nobody asked you. If the answer contains “I was asked to”, it is not an initiative answer and you have spent the question.
- Tell me about a time you spotted something that needed doing and did it.
- Describe a situation where you went beyond what was required.
- Give an example of when you improved a process.
Adaptabilitynamed in 8.8% of adverts
They are listening for: What you did when the plan broke — not that you stayed positive. “Remained calm” is a feeling, not a behaviour, and behaviours are what get ticked.
- Tell me about a time when something changed at short notice.
- Describe a situation where you had to learn something quickly.
- Give an example of when you had to change your approach partway through.
Time managementnamed in 5.9% of adverts
They are listening for: The decision about what not to do. Anybody can list four commitments; the answer is which one you dropped or delayed, and why.
- Tell me about a time you had several deadlines at once.
- Describe a situation where you had to prioritise.
- Give an example of when you missed a deadline — what happened?
Attention to detailnamed in 19.1% of adverts
They are listening for: A specific error you caught or prevented, with the consequence it would have had. Without the consequence it is a story about proofreading.
- Tell me about a time you spotted a mistake others had missed.
- Describe a situation where accuracy really mattered.
- Give an example of how you check your own work.
Leadershipnamed in 3.2% of adverts
They are listening for: Getting something done through people who did not have to do what you said. For a graduate that is a society or a group project, not a job title.
- Tell me about a time you led a group.
- Describe a situation where you had to motivate people.
- Give an example of when you had to deal with disagreement in a group you were leading.
A full answer, line by line
Everyone knows STAR. What nobody shows is a whole answer of the right length — this is about 160 words, roughly a minute spoken. Most graduates give either forty words, which cannot contain a result, or four hundred, by which point the interviewer has stopped writing.
Tell me about a time you worked as part of a team to achieve something.
S — Situation
In my final year I was in a five-person group writing a consultancy report for a local charity. Two people dropped the module in the second week, three weeks before the deadline.
Two sentences. The interviewer needs enough to picture it and nothing more — every extra sentence here is one you do not get for the result.
T — Task
We still had to deliver the full report, and the three of us left had very different strengths — one strong writer, one who could handle the data, and me somewhere in between.
Task is the shortest part and most people skip it entirely. One sentence saying what had to happen and what made it hard.
A — Action
I suggested we stop splitting the work evenly and split it by what each of us was fastest at instead. I took the client interviews and the structure, because I was the one who had met them. I set a Tuesday check-in so nobody disappeared for a fortnight, and I rewrote the data section headings so the writer could work on it without understanding the analysis.
This is where the marks are and where most answers are thinnest. Three or four specific decisions, all of them yours, all saying “I”. Notice there is no claim to have led — the behaviour says it.
R — Result
We submitted two days early and it was the highest mark in the cohort. The charity used the recommendation on volunteer scheduling, which I know because the coordinator emailed about it in the summer.
A number and an outcome that outlived the assignment. The last sentence is the strongest thing in the answer because it is checkable and almost nobody has one.
You need five stories, not twenty
The advice to "prepare an example for each competency" is why people arrive with eight half-remembered stories and tell all of them badly. You will face four to six questions. A single situation, told from a different angle, answers two or three competencies — the same group project is a teamwork answer, an adaptability answer or a time-management answer depending on which part you tell.
So build a grid instead: five situations down the side, the competencies across the top, and a mark where each one can reach. Five rich stories you can tell properly beats twenty you half-remember, and the grid shows you the gap before the interview rather than during it.
| A situation you have | Competencies it can answer |
|---|---|
| The group project that lost two members | Teamwork, Adaptability, Leadership, Time management |
| The service desk job and the crib sheet | Communication skills, Initiative, Adaptability |
| The society ticketing that kept double-selling | Problem solving, Initiative, Attention to detail |
| The dissertation data cleaning | Attention to detail, Problem solving, Time management |
| The term with three deadlines and a shift pattern | Time management, Adaptability, Teamwork |
Those five cover all eight competencies above, several of them twice. If a column has no mark against it, that is the one to go looking for — and it is usually somewhere you did not think counted.
Five ways a good story scores badly
Saying “we” for the whole answer
The sheet in front of the interviewer has your name on it, not the group's. If they cannot tell which decisions were yours, there is nothing to tick. Describe the group in one sentence, then say “I” for the rest.
Describing a responsibility instead of an occasion
“I was always the one who organised things” is not an answer, because it has no situation, no action and no result. They asked for a time. Pick one.
Stopping before the result
The most common way a good story scores badly. People spend ninety seconds on the setup, realise they are talking too long, and finish with “and it went well”. Protect the last fifteen seconds — that is the part being scored.
Choosing the most impressive story rather than the most relevant one
An answer about a prestigious internship that does not demonstrate the competency scores below an answer about a bar job that does. They are ticking a behaviour, not ranking your CV.
Running to four minutes
About a minute is right — roughly 150 to 200 words. Beyond two minutes the interviewer stops writing, and what they wrote down is what gets scored after you leave.
What is counted here and what is judgement
Counted: which competencies UK graduate adverts name, across 12,914 live listings read from employers' own careers pages on 5 November 2026. That is the basis for saying these eight are the ones to prepare.
Not counted: everything about the interview itself. Only 0.7% of adverts say outright that their interview is competency-based, which is far too few to describe how employers run them — so the scoring sheet, the answer length and the failure modes are experience and judgement, not findings. We would rather label that than imply a dataset we do not have.
Getting to the interview is the other half
None of this matters until an application gets through. Gradovio ranks every live graduate role against your CV, writes the CV and cover letter against the specific advert, and fills the form on the employer's own site — so the time goes on preparing for the interviews rather than on getting them.
