What’s a Competency-Based Interview?

A competency-based interview (also called behavioural or criterion-based interviewing) is designed to find out how you’ve handled real-life situations at work — because how you’ve acted in the past is usually the best indicator of how you’ll perform in the future.

In these interviews:

  • The interviewer knows exactly what skills and behaviours are needed for the job.

  • Questions are based around those key areas (called competencies).

  • Every candidate is asked similar questions to keep things fair and consistent.

Because of this structured approach, interviewers can make much more accurate hiring decisions — around three times more accurate than traditional interviews!

How to Get Ready

Try to prepare two examples for each competency listed in the job description.
For example: teamwork, leadership, problem-solving, or communication.

The easiest way to structure your answers is to use the STAR model, which helps you stay clear and focused.

STAR stands for:

  • S – Situation: What was going on? Give some context.

  • T – Task: What was your goal or what needed to be done?

  • A – Action: What did you do? (Focus on your contribution.)

  • R – Result: What happened in the end? What was the outcome or impact?

Most interviewers will start with open questions like:

“Tell me about a time when…”
This is your cue to use STAR to guide your answer.

Example Competency Questions

Here are some examples of the types of questions you might be asked:

  • Tell me about a time you motivated someone or a team to achieve a goal.

  • Describe how you made sure your team knew exactly what needed to be done.

  • Give an example of when you improved a process or service for customers.

  • Tell me about a time you built a strong relationship with a stakeholder.

  • Describe a situation where you helped resolve a disagreement at work.

  • Give an example of a time you had to make a quick decision.

  • How did you handle a challenge or setback in your last role?

  • What did you do in your last job to be effective?

  • Describe a time you had to adapt your style to work better with someone.

  • Tell me about a time you contributed to great teamwork.

  • Share an example of when you influenced others in a positive way.

  • How did you deal with a task that you found boring or repetitive?

  • Tell me about a project or presentation you were proud of.

  • Give an example of solving a difficult problem or working with limited information.

Remember

These questions are designed to help you show what you’re capable of — not to catch you out.
The STAR method is your best friend here. It keeps your answers focused, structured, and easy to follow.

If the interviewer asks follow-up questions, that’s a good sign — it means they’re interested in hearing more about your experience.
