Competency-Based Interview

What it is, why it matters for you as a candidate, and how to prepare for it.

Definition

A competency-based interview scores you against a published list of competencies such as leadership, communication or problem solving. Each question targets one competency, and the interviewer marks your evidence against defined levels. The format is standard in UK public sector, healthcare, banking and graduate recruitment, and it overlaps heavily with behavioral interviewing.

What Competency-Based Interview means in practice

Employers using this format usually publish the competency framework in advance, sometimes with the exact indicators being assessed. Questions are phrased as 'Give me an example of when you...' and each carries scripted probes to test depth. Interviewers score every competency separately, often out of four or five, and a minimum score per competency may be required regardless of the total. Sessions run forty-five to ninety minutes and cover four to six competencies. Application forms in this system often ask for written competency examples first, and those are scored the same way.

Why it matters for candidates

Because the criteria are published, this is the most preparable interview format that exists. The trap is thin evidence: one story stretched across three competencies, or an example where the difficult part was done by someone else. Scorers need your actions, in your words, with a result attached. Reusing the same project for every answer also caps your score, because the framework rewards breadth of evidence as well as depth.

How to prepare

  • Find the published competency framework and its indicators before applying.
  • Prepare a distinct example for every competency listed.
  • Write each example so your actions and the result land clearly.
  • Use the framework's own vocabulary when describing what you did.
  • Have a second example per competency ready for the inevitable probe.

Example

How it typically plays out

A public sector role lists 'making effective decisions' as a competency, with indicators about weighing evidence and consulting stakeholders. Asked for an example, the candidate describes a procurement choice: the options, the data gathered, who was consulted, the decision made under a deadline and the money saved. When the interviewer probes what they would do differently, they name one stakeholder they should have consulted sooner, which is itself an indicator being scored.
