Eight Electrical Supervisor interview questions, and what the interviewer is thinking

1. How do you plan and allocate labour on an electrical package to keep to programme?

Why they ask: Supervisors are judged on productivity and delivery, so they need to see your planning method.

2. How do you make sure that your team's work is inspected and quality-checked before it is covered up or handed over?

Why they ask: Quality control prevents expensive rework and compliance failures.

3. One of your electricians tells you the main contractor's site manager has asked him to do extra work that is not on the programme. How do you handle it?

Why they ask: Supervisors need to manage variations and relationships with main contractors.

4. Tell me about a time you had to deal with a safety issue involving someone in your team.

Why they ask: They need to see how you act on safety leadership when it involves your own people.

5. What are your responsibilities as an electrical supervisor under the Electricity at Work Regulations 1989 and when managing live or isolated systems?

Why they ask: They check your legal understanding as the person in charge on site.

6. Your team is behind programme and the site manager wants you to put two electricians in an area where another trade is working. What do you consider?

Why they ask: This tests balance between delivery pressure, safety and productivity.

7. What documentation do you expect to see completed on an electrical package before practical completion?

Why they ask: Handover documents are essential for compliance and they want to test your knowledge.

8. What makes a good electrical supervisor, and how do you see your role differing from a lead electrician?

Why they ask: They want to know you understand the step up into supervision.

A sample answer to question 1

How do you plan and allocate labour on an electrical package to keep to programme?

I begin with the programme and the drawings, then break the work into areas and tasks with realistic man-hours based on the estimate. I match people to jobs by skill, putting qualified electricians on terminations and containment lead hands on first fix, and improvers and apprentices with someone who can supervise them. I plan material deliveries ahead so nobody is waiting, and check the three-week look-ahead with the site manager every week. Each morning I give a short briefing with the day's targets, hazards and who is working where, and I walk the areas at the end of the day to measure progress. If we slip, I look at why before adding labour, because that often fixes the actual problem. I track actual hours against planned in a simple sheet, so I can flag a problem early to my contracts manager.

Common mistake to avoid: Adding labour without finding the cause; planning without checking material availability
