Competency-Based Interview Questions: The Complete Guide

What competency-based interviews really assess, the questions to expect for each competency, and how to prepare evidence that scores.

9 min read · Updated 14 August 2026

Competency-based interviews (also called behavioural or structured interviews) are built on a simple premise: past behaviour predicts future behaviour. Instead of asking how you'd handle a hypothetical, the interviewer asks for real examples of when you've already demonstrated the skills the job needs.

They're the dominant format in graduate schemes, the public sector, large corporates and most structured hiring processes — precisely because they're fairer and more consistent than a free-flowing chat. Every candidate is asked about the same competencies and scored against the same rubric.

The competencies employers assess most

Different employers publish different frameworks, but most questions map to this handful of underlying competencies:

Teamwork and collaboration — working effectively with others, handling different working styles.
Leadership and influence — motivating people, driving outcomes without always having authority.
Problem-solving and decision-making — structured thinking, judgement under uncertainty.
Communication — explaining clearly, listening, adapting to your audience.
Resilience and adaptability — staying effective under pressure and through change.
Planning and organisation — managing time, priorities and competing demands.
Customer or stakeholder focus — understanding and serving the people you work for.

How to spot a competency question

Competency questions almost always ask for a specific past example. Listen for the opening: "Tell me about a time when…", "Give me an example of…", "Describe a situation where…", "When have you had to…".

That phrasing is your cue to reach for a concrete story from your past — not a hypothetical, not a general statement about how you "always" behave. The single most common mistake is answering a "tell me about a time" question with a theory of how you'd behave in general.

Example questions by competency

Teamwork: "Tell me about a time you worked in a team to deliver something difficult."
Leadership: "Describe a time you took the lead when it wasn't expected of you."
Problem-solving: "Give me an example of a complex problem you solved. How did you approach it?"
Communication: "Tell me about a time you had to explain something complicated to someone."
Resilience: "Describe a setback you faced and how you responded."
Planning: "Tell me about a time you managed competing priorities or deadlines."
Customer focus: "Give me an example of going out of your way to help a customer or colleague."

How to prepare

A reliable four-step method that beats improvising every time:

Find the competencies. Check the job description and the employer's website — many publish their exact competency framework or values. These are what you'll be scored against.
Map your evidence. For each competency, write down one or two real examples from work, study, volunteering or extracurriculars that demonstrate it.
Structure each example with STAR. Situation, Task, Action, Result — most of your words on Action, always finishing with a measurable result.
Practise aloud. Say your answers out loud, ideally to another person or a mock interviewer, until they're fluent but not scripted.

Turning evidence into a score

Remember that the interviewer is filling in a scoring sheet as you talk. A strong competency answer gives them everything they need to tick every box: a clear situation, your specific role, the actions that demonstrate the competency, and a result that proves it worked.

If you finish an answer and the interviewer could not confidently score the competency, the answer has failed — however interesting the story was. Prepare with that scoring sheet in mind, and you'll consistently outperform more experienced candidates who wing it.

Frequently asked questions

What is a competency-based interview?

A structured interview where you're asked for real past examples of demonstrating specific skills (competencies), on the principle that past behaviour predicts future performance. Answers are scored against a consistent rubric.

How is a competency interview different from a normal interview?

Competency interviews ask for specific past examples rather than hypotheticals or opinions, and every candidate is scored against the same defined competencies — making the process more structured and consistent.

How many examples should I prepare?

Prepare one or two strong examples for each competency in the job's framework — typically five to seven competencies, so around 8–12 flexible stories that you can adapt across questions.

Practise these questions out loud

Reading answers isn't the same as delivering them. GetPrepPro runs spoken mock interviews tailored to your CV and the exact job you're targeting, then scores every answer against a STAR-based rubric.
