Key Skills to Display as a Clerk of Works to Excel in Your Next Job Interview
Posted by Hugh Duffield, Graduate Recruitment Director Consultant on Wednesday, September 24, 2025
As a Clerk of Works, you safeguard quality and represent the client’s interests on site. The COW and QTI professionals who thrive in this role rely on people skills, technical expertise and hands-on experience, finding clear, actionable steps to resolve complex situations. Here are some practical tips so that you can approach your next Clerk of Works job interview with confidence.
Showcase Your Value
Be prepared to give examples of how your observations turned into actions that saved time, budget or rework. Candidates that can lucidly explain their professional achievements leave a strong impression.
Action step: Make a list of how you added value to a previous job, whether that’s reduced snag closure times, avoided rework, or smoother handovers; and use quantifiable metrics to impress your interviewer.
Clear Communication
Interviewers don’t just require a well-formatted CV; they need someone who can listen to questions and clearly articulate answers. That doesn't mean you have to be a Shakespearean-level orator, but speaking in a way that is concise, relevant and level-headed goes a long way in demonstrating your professionalism.
To expand on these points:
- Conciseness is crucial because interviewers won’t remember long rambling responses and your original point could get lost
- Keeping answers and discussions relevant ensure you are addressing the question head-on. Going off at a tangent can give the wrong impression
- Keep emotions out of it, interviewers don’t enjoy speaking with moody or downbeat candidates and don’t usually want to hear fierce and lengthy criticisms of current employers (even if justified)
Action Step: Rehearse your answers to generic interview questions so that on the day you sound credible as a Clerk of Works, e.g., “tell me about a project you’ve worked on recently”, “What makes a good Clerk of Works in your view?”, etc.
Technical Competence
A Clerk of Works is expected to know the details of construction quality, compliance, and safety inside and out. In interviews, expect to be quizzed on building regulations, British Standards, NHBC requirements, or JCT contracts where appropriate. Proving your knowledge of inspection methods, materials, and defect identification shows you can be trusted to uphold standards on-site.
Action Step: Brush up on any of these areas you’re less familiar with prior to the interview, so nothing catches you out.
