Opening & warm-up
How interviewers test your communication and preparation right from the start.
Walk me through your electrical engineering career.
I've been an electrical engineer for seven years, three in Oman. Started in electrical design at an Indian consultancy, transitioned to project execution, and for the past three years I've been electrical engineer at an Omani contractor on construction projects. My remit: electrical design coordination, contractor management on site, testing and commissioning. Chartered Engineer path plus relevant credentials.

Behavioural (STAR)
Past-experience questions. Use the STAR framework: Situation, Task, Action, Result.
Tell me about a major project.
Last year I led electrical execution for a major commercial building: HV intake, distribution, lighting, emergency systems. Twelve months of project work. Live and operational. Electrical engineering on construction projects succeeds on discipline and field engagement.
Real delivery.
Describe a technical issue.
Voltage drop calculations showed marginal compliance on a long feeder run. Investigated alternatives: larger conductor vs intermediate distribution. Cost-effective solution: intermediate distribution. Code compliance achieved with better operability. Engineering judgement plus code adherence.
Engineering work.
Tell me about contractor management.
Electrical subcontractor was slow on installation. Engaged their PM with specific recovery plan. Mobilised additional resources. Schedule recovery achieved. Subcontractor management is firm but fair.
Subcontractor management.

Technical & role-specific
Questions that test your specific skills for this role.
Walk me through electrical design coordination.
Load assessment. Distribution architecture. Equipment selection. Cable sizing including voltage drop and short-circuit. Protection coordination. Lighting design. Emergency systems. Coordination with mechanical (motor loads), instrumentation (control power), building services. Documentation comprehensive.
Design depth.
Describe testing and commissioning.
Pre-energisation: visual, insulation resistance, continuity. Energisation: phase sequence, voltage levels. Protection testing per setting. Load testing where appropriate. Documentation per ITP. T&C is the integrity verification before handover.
T&C depth.
How do you handle protection coordination?
Short-circuit study. Protective device coordination per time-current curves. Selectivity verified. Settings calculated and documented. Critical for safety and minimising disruption from faults. Protection coordination is engineering applied to fault management.
Protection depth.
Category
Situational
Hypothetical scenarios designed to test your judgement and approach.
Energisation test reveals an issue. What do you do?
Don't energise further until cause is understood. Methodical diagnosis. Engineering review if non-obvious. Fix and retest. Energisation issues caught at T&C are gifts; energisation issues missed become operational hazards.
T&C discipline.
Category
Cultural fit & motivation
Why this role, why this company, and how you work with others.
How do you handle site teams?
Site teams work under field conditions. Respectful regardless of role. Consistent on standards. Clear communication. Site relationships matter for sustained quality.
Site relationships.

Closing
The final stretch. Often where deals are won or lost.
What are your salary expectations?
For a senior electrical engineer role on construction at an Omani contractor I'd target OMR 1,400 to 1,900 total package depending on project portfolio and on-call. I'd expect annual bonus and certification budget. I'm on 30-60 days' notice. Beyond pay I'd value the project quality.
Range preference.
