About the role
This interview is for an engineer who can carry a solar PV project from design assumptions to tested handover. Expect technical scenarios on hybrid systems, quality control, substitutions and commissioning, alongside questions about schedule and client decisions.
How to prepare
- Revise load profiling, array sizing, inverter selection, storage assumptions and protection for hybrid PV systems.
- Prepare a project example that shows how you managed design, procurement and installation dependencies.
- Review the site inspections and electrical tests you use before energisation and handover.
- Practise comparing an equipment substitution on technical, commercial and warranty grounds.
- Be ready to explain how you record design changes and secure stakeholder approval.
Common mistakes
- Sizing from appliance names alone without asking about operating hours, peaks and growth.
- Accepting substitutions based only on purchase cost.
- Describing handover without test records, defect closure or operating guidance.
- Giving a schedule answer that ignores procurement lead times and site access.
