What is a Competency-Based Interview & How to Prepare

Posted on Wednesday, August 5, 2026 by Marie L

Interviews can feel nerve-racking at the best of times, especially when you're not quite sure what questions to expect. One format that many employers use when recruiting for office-based roles is the competency-based interview. Understanding how these interviews work can help you feel more confident and give you the best chance of success.

What is a Competency-Based Interview?

A competency-based interview focuses on the specific skills, behaviours, and attributes needed for a role. Rather than simply discussing your CV or previous job titles, the interviewer will ask you to provide real examples of situations where you've demonstrated particular competencies.

These competencies might include things from communication to leadership or problem-solving to customer service. Anything that is needed for success in the role.

The aim is to understand how you've behaved in workplace situations and whether you're likely to perform well in this job.

What Questions Might You Be Asked?

Competency-based questions often start with phrases such as:

  • "Tell me about a time when..."
  • "Give me an example of..."
  • "Describe a situation where..."

For example, you might be asked:

  • Tell me about a time you had to deal with a difficult client.
  • Give an example of when you worked under pressure.
  • Describe a situation where you had to prioritise competing tasks.
  • Tell me about a time you resolved a problem within your team.

The interviewer is looking for evidence, so it's important to provide specific examples rather than general statements.

Use the STAR Method

One of the most effective ways to answer competency-based questions is by using the STAR method.

·       Situation: Briefly explain the context.

·       Task: Describe your responsibility or objective.

·       Action: Explain what you did.

·       Result: Share the outcome and what was achieved.

This structure helps keep your answer clear, concise, and focused on your contribution.

Prepare Examples in Advance

A common mistake is waiting until the interview to think of examples. Instead, spend some time reviewing your experience beforehand.

Think about situations where you've:

  • Solved a problem
  • Managed conflicting priorities
  • Improved a process
  • Handled a challenging conversation
  • Worked as part of a team
  • Delivered excellent customer service
  • Learned a new skill quickly

Don’t over-script your answer, just have some good scenarios up your sleeve so you’re not trying to remember them on the spot.

Tailor Your Preparation to the Role

Always read the job description carefully before your interview. Employers often highlight the key competencies they're looking for. The more relevant your examples are, the stronger your answers will be.
