How to Answer — The STAR Method
Use the STAR structure to answer behavioural questions with a strong story:
- Situation: What was the context?
- Task: What was your responsibility?
- Action: What did you do?
- Result: What outcome/impact followed? (with numbers if possible)
What to Highlight in the Interview
- ✓State which area you are experienced in (industrial, building, maintenance, installation).
- ✓List your qualifications (NVQ / City & Guilds, 18th Edition, CSCS/ECS card, high-voltage authorisation if any).
- ✓Add the site/equipment types you have worked with (panels, motors, PLC).
- ✓Emphasise health and safety and accident-free working.
What to Avoid

Frequently Asked Questions
How should I prepare for an interview?
Study likely questions in advance, prepare a concrete example from your own experience for each (using STAR) and rehearse out loud.
How much should I talk in my answers?
Ideally 60–90 seconds per question. Too short seems disengaged; too long seems unfocused.
What if I get a question I do not know?
Be honest; say you do not know, but add how you would learn it or a similar experience. Making things up is the biggest mistake.
