What it is
Competency interviews are a structured form of behavioural interview where the company has explicit competency frameworks — defined behaviours at specific levels. Civil service has 12 behaviours (changing, delivering, communicating, etc.) with explicit examples at each grade. NHS has the NHS Leadership Academy framework. Banks have technical + behavioural frameworks. The interviewer asks specific behavioural questions and scores you against the documented competencies, often using a numerical scale.
Who uses it
UK civil service Fast Stream and grade-track interviews. NHS leadership and grade interviews. Large UK banks (HSBC, Barclays, Lloyds, NatWest) for analyst and graduate hiring. Major UK corporates with mature HR functions. Some Big 4 graduate schemes. The format is rare at startups and scale-ups but standard at established UK employers.
How to prepare (step-by-step)
- 1 Get the company's competency framework before the interview — civil service publishes its Success Profiles publicly; companies usually share theirs on request.
- 2 Map your STAR stories to specific competencies in the framework.
- 3 Practise answering questions like 'Tell me about a time you demonstrated [competency]' with the relevant story.
- 4 For UK civil service specifically, study the grade descriptors — examples of behaviour at the grade you're applying for.
- 5 Prepare evidence for technical competencies separately if the framework includes them.
- 6 Practise concise answers — competency interviews often have many questions in limited time.
- 7 Prepare to explain why your story demonstrates the specific competency they're scoring — connect dots explicitly.
What this format assesses
- →Whether your evidence demonstrates the documented competencies clearly
- →Whether you operate at the right level for the grade you're applying for
- →Consistency of evidence across multiple competencies (does your story bank suggest a real career or invented examples?)
- →Specific behaviours articulated explicitly, not implied
Common mistakes
- ✗Vague answers that touch on multiple competencies without demonstrating any specifically
- ✗Stories that don't match the competency level (junior examples for senior roles)
- ✗Not connecting the story explicitly to the competency — leaving the interviewer to guess
- ✗Repeating the same story for multiple competencies
- ✗Skipping the framework prep — competency interviews can't be ad-libbed effectively
Recruiter pro tip
The single most important move in UK competency interviews — especially civil service and NHS — is getting the framework before the interview. Most companies share the competencies they're scoring on if you ask. Civil service publishes Success Profiles publicly. The candidates who succeed are the ones who treat each competency as a discrete checklist item with prepared evidence, not the ones who try to generally talk about themselves.
