Interview Questions to Ask a Mason / Bricklayer Candidate
Questions that surface real evidence of structural precision and craftsmanship verified by real completed work — plus what to actually listen for in the answer, not just whether they say the right buzzwords.
1. How do you set out and build a straight, plumb brick wall from a drawing?
What to listen for: Uses datum levels, line and pins, spirit level and gauge rod, checks courses frequently, and corrects problems early.
2. What do you look for when mixing mortar for different conditions such as hot dry days or frost?
What to listen for: Understands the right mix and consistency, protection from rapid drying or freezing, and when work should stop or be covered.
3. While working on scaffolding you notice a loose board and the site supervisor is not around. What do you do?
What to listen for: Stops using the area, tags or reports the hazard, tells the supervisor or scaffolder, and does not carry on and hope.
4. You find that a wall you built yesterday is slightly out of line at one corner. Do you tell anyone, and what do you do?
What to listen for: Reports honestly, assesses whether it can be corrected, rebuilds if needed, and accepts the cost of the fix instead of hiding it.
5. What would you do in your first 30 days in this mason / bricklayer role?
What to listen for: Whether their plan is grounded in the role's actual must-haves (bricklaying/block-laying technique and blueprint reading) or generic ("get to know the team"). Specificity here signals real understanding of the job, not just interview prep.
6. Why are you leaving your current role, and why this one specifically?
What to listen for: Forward-looking motivation tied to something concrete about this role, versus badmouthing a past employer or vague dissatisfaction. Watch for whether their reasons actually match what this role offers.

Frequently asked questions
How many of these questions should I ask in one interview?
3-4 is realistic for a 30-45 minute interview once you leave room for follow-ups and the candidate's own questions. Divide competencies across panel members rather than every interviewer asking all of them — see the Interview Scorecard tool for a structured version of this.
