Negotiation tips

1. Research market rates for the role and location. Use salary aggregators and sector reports.
2. Ask clarifying questions: work schedule, allowances, tax implications.
3. Negotiate on total package (training, travel, housing) if base salary has limited flexibility.
4. Be professional and justify requests with market evidence and your unique skills.

Acceptance, onboarding and probation – what to expect

Upon offer you should expect:

1. A written contract with role, salary, probation period and mobilisation details.
2. A pre-employment screening pack (references, background checks, medical).
3. Onboarding plan: site inductions, safety briefings, HR orientation, IT access.
4. Probation review at 3 or 6 months, with clear KPIs.

Prepare to be proactive: ask for an induction schedule, required PPE and any pre-start reading (SOPs, safety manuals).

Career progression and specialisations

Energy careers offer many pathways:

1. Technical ladder: Technician > Senior Technician > Engineer > Principal Engineer > Technical Lead.
2. Management track: Project Engineer > Project Manager > Programme Director.
3. Commercial track: Buyer > Contracts Manager > Commercial Director.
4. Specialist track: HSE Advisor > HSE Manager > Head of HSE.
5. New energy specialities: battery technology, hydrogen, carbon capture, energy markets.

Use employer training, secondments and professional certifications to accelerate progression. Consider academic upskilling (MSc, part-time degrees) if aiming for specialised roles.

Five model STAR answers for common energy sector interviews

1. Handling a Major Equipment Breakdown

Question: “Tell me about a time you handled an unexpected equipment failure in the field.”

Situation:
While working as a field technician at a power generation plant, one of the main transformers unexpectedly failed during peak load hours. This posed a significant risk of power interruption to key clients.

Task:
I was responsible for diagnosing the issue, restoring service quickly, and ensuring minimal disruption to operations.

Action:
I immediately conducted a root-cause assessment using diagnostic tools, isolated the affected circuit, and coordinated with the control room to reroute power flow. Then, I led a small team to replace the damaged bushing and perform insulation resistance tests.

Result:
We restored power within three hours – 50% faster than the standard response time. The management commended our quick response, and the incident response procedure I documented was later adopted as part of the company’s emergency protocol.

2. Improving Energy Efficiency

Question: “Can you describe a time you helped improve operational efficiency or reduce energy loss?”

Situation:
At my previous job in a solar installation company, our monthly audit revealed that several systems had lower-than-expected energy yields due to wiring losses.

Task:
I was assigned to identify causes and recommend ways to improve system efficiency.

Action:
I performed on-site performance ratio tests, analyzed inverter data logs, and discovered voltage drops due to undersized cable runs. I proposed using higher-gauge cables and optimizing inverter placement.

Result:
After implementation, system performance improved by 12%, customer satisfaction scores increased, and the company integrated my solution into its design standards for future installations.

3. Managing a Safety Incident

Question: “Give an example of how you handled a safety issue on-site.”

Situation:
During a maintenance shift at an oil and gas facility, I noticed a coworker about to enter a confined space without proper gas testing.

Task:
I had to ensure the safety of my colleague and enforce compliance with safety regulations.

Action:
I stopped the activity immediately, reminded the team of the confined-space entry protocol, and performed gas detection tests. I then reported the near-miss incident to HSE (Health, Safety & Environment) for investigation and helped conduct a refresher toolbox talk for the team.

Result:
No injuries occurred, and the HSE team recognized the quick response. Afterward, our department recorded six months without a single safety violation.

4. Leading a Technical Project

Question: “Describe a time when you led a technical project or installation.”

Situation:
As a junior engineer, I was appointed to lead a small team for installing a 5MW solar mini-grid in a rural community.

Task:
My role was to coordinate the installation, ensure compliance with safety and electrical standards, and meet project deadlines.

Action:
I divided the project into phases – site survey, civil works, electrical installation, and commissioning. I scheduled daily team briefings, maintained material logs, and liaised with the local utility for interconnection approval.

Result:
The project was completed 10 days ahead of schedule and under budget. It powered 500 homes and small businesses, earning national recognition under a government renewable initiative.

5. Dealing with a Difficult Client or Stakeholder

Question: “Tell me about a time you had to manage a difficult client or stakeholder.”

Situation:
While servicing industrial backup generators for a manufacturing client, they complained repeatedly about frequent shutdowns despite recent maintenance.

Task:
I needed to identify the root cause and restore the client’s confidence in our service.

Action:
I conducted a detailed load test, reviewed the generator’s fuel quality and maintenance history, and discovered contaminated fuel filters as the real issue. I replaced the filters, installed a fuel-water separator, and educated the client’s staff on proper fuel storage.

Result:
The problem was resolved permanently. The client renewed their annual maintenance contract and referred two other companies to our service.
