Competency Interview Preparation Guide: How to Demonstrate the Skills Employers Value
4th November 2025
Modern interviews look beyond technical delivery to assess how you think, interact and contribute within a team and organisation. While your qualifications and track record matter, the ability to demonstrate your behaviours, approach and judgement often separates successful candidates from the rest. This competency interview preparation guide identifies the core areas to focus on and how to present your experience with clarity and confidence.
1. Communicate your experience through real-world examples
Employers expect more than role descriptions; they want evidence of how you operate in practice. Rather than listing tasks, describe situations you encountered, your responsibilities, the actions you took and the results achieved. Using a structured approach such as STAR (Situation, Task, Action, Result) can help you present your experience clearly and show how you add value under real conditions.
2. Demonstrate behavioural and interpersonal strengths
Interviews increasingly evaluate qualities such as leadership, teamwork, resilience, adaptability and stakeholder management. When preparing, reflect on examples that show how you collaborate, make decisions, adapt under pressure and support successful delivery. Draw on experiences where you influenced outcomes, resolved challenges, adapted plans or balanced competing priorities. Employers want reassurance that you can integrate well into project teams and wider organisational culture.
3. Show an understanding of safety, governance and risk
Many roles require disciplined approaches to safety, compliance, quality and risk management. Be prepared to discuss how you have contributed to safe working environments, upheld governance and followed structured processes. Demonstrating accountability and a safety-first mindset reinforces your professional approach and supports employer confidence in your judgement.
4. Prepare in depth and present confidently
Competency interview success comes from thoughtful preparation, not memorisation. Review role requirements, research the organisation and prepare a diverse portfolio of examples across different work scenarios. Practise articulating your experience concisely, maintaining clarity and professionalism throughout. As you apply this competency interview preparation guide, focus on demonstrating not only what you achieved, but how you achieved it.
