A competency-based interview is a way of evaluating if a candidate’s skills and competencies align with the essential requirements of the role outlined in the person specification.

Competency-based interviews work on the principle that past performance is the best predictor of future behaviour.

The questions are designed for you to provide evidence of your skills and experience, for example, “Can you give an example of when…?”, “Tell us about a time when you…”.

A good way to structure your answers is to use the STAR technique:

Situation – briefly outline the situation

Task – what was your objective/task?

Action – what did you do? how did you do it?

Result – what was the outcome, impact and what did you learn?
