One of the Most Common Energy Interview Questions
“Tell me about a technical problem you solved” is one of the most common questions in energy and engineering interviews.
It appears straightforward, but many candidates give answers that are too vague to demonstrate their competence.
They describe what the team did, jump directly to the solution or provide no evidence that the problem was safely and successfully resolved.
A strong response should show technical reasoning, personal responsibility, safe working and a verified outcome.
What Is the Interviewer Assessing?
The interviewer is not only interested in the fault itself.
They are usually assessing whether you can:
- Recognise and define a technical problem
- Gather relevant information
- Investigate systematically
- Work within your competence and authority
- Apply the correct safety controls
- Communicate with other personnel
- Make evidence-based decisions
- Verify that the corrective action worked
- Learn from the experience
The example does not need to involve a major emergency or complex equipment failure. A routine problem can still provide a strong answer if it demonstrates sound judgement and clear personal involvement.
Choose the Right Example
Select an example that is relevant to the position and that you understand well enough to discuss in detail.
Suitable examples might include:
- Investigating abnormal equipment performance
- Identifying the cause of repeated trips or alarms
- Resolving a commissioning problem
- Discovering an installation or quality defect
- Correcting an instrumentation issue
- Responding to a failed test
- Preventing a maintenance task from creating a further problem
- Challenging an unsafe or technically incorrect approach
Avoid choosing an example where you cannot clearly explain your own contribution.
Use a Five-Part Structure
A useful structure is:
Situation
Briefly explain the equipment, system or task and the problem that occurred.
Include enough context for the interviewer to understand the issue, but avoid unnecessary project history.
Responsibility
State what you were personally responsible for.
Explain whether you were expected to investigate, supervise, inspect, repair, test, coordinate or escalate the problem.
Safety
Describe the controls that applied before and during the work.
These may include risk assessment, permit-to-work requirements, process or electrical isolation, stored-energy controls, communication with operations and verification that the equipment was safe to work on.
Only mention controls that were genuinely relevant to the example.
Action
Explain your investigation in a logical sequence.
Describe:
- What information you reviewed
- Which checks you completed
- What possible causes you considered
- How the evidence influenced your decisions
- When you involved other people
- What corrective action was taken
Do not simply provide a list of everything that could theoretically cause the problem. Focus on what you actually checked and why.
Result
Explain how the outcome was verified.
Where relevant, describe:
- The confirmed cause
- The repair or corrective action
- Testing completed before reinstatement
- The equipment’s performance after start-up
- Documentation or handover
- Any action taken to prevent recurrence
Weak-Answer Example
“A pump had low flow, so we checked the strainer. It was blocked, so we cleaned it and put the pump back into service.”
This may be technically possible, but it leaves several questions unanswered:
- How was the reduced flow confirmed?
- What was the candidate personally responsible for?
- Were other possible causes considered?
- How was the equipment made safe?
- Who authorised the intervention?
- How was the repair verified?
- Did the flow return to its expected condition?
The answer reaches the solution too quickly and provides little evidence of the candidate’s judgement.
Stronger-Answer Example
“During operation, a centrifugal pump was showing lower-than-expected flow. I was responsible for completing the initial assessment and supporting the fault-finding process.
I first confirmed the reported condition by reviewing the available flow and pressure information and comparing it with the normal operating range. I then checked the relevant operating conditions with the control-room operator, including the supply condition and valve line-up.
The available information suggested a possible restriction on the suction side, but I did not assume that was the only cause. Before any intrusive inspection, the task was reviewed, the required permit and isolation controls were applied, and the safe condition of the equipment was verified in accordance with the site procedure.
The inspection identified partial obstruction of the suction strainer. It was cleaned and inspected before the system was reinstated. Following the authorised return to service, we monitored the pump and confirmed that flow and pressure had returned to the expected operating range. The work and findings were recorded and communicated to operations.”
This answer is stronger because it demonstrates a logical investigation, relevant safety controls, personal involvement and verification of the outcome.
It should still be adapted to reflect what actually happened. Candidates should never claim checks, responsibilities or results they were not involved in.
Avoid These Common Mistakes
The following habits weaken otherwise competent examples.
Describing Only What “We” Did
Teamwork is important, but the interviewer needs to understand your individual contribution.
Use “we” when describing a genuine team activity and “I” when explaining your own checks, decisions and actions.
Jumping Straight to the Solution
A correct diagnosis is not enough. Explain how you reached it and why the evidence supported it.
Giving a Textbook Fault List
Listing every possible cause can make the answer sound memorised.
Prioritise the most credible causes using the information available at the time.
Treating Safety as a Closing Statement
Do not finish with “and obviously, we worked safely.”
Explain where risk assessment, permits, isolation, verification or communication influenced the work.
Forgetting the Result
The task is not complete simply because a component was repaired or replaced.
Explain how the equipment or system was tested and how successful performance was confirmed.
Exaggerating Your Authority
Be clear when decisions required approval from a supervisor, operations, engineering or an authorised person.
Knowing when to escalate is evidence of judgement—not weakness.
Prepare Examples, Not Scripts
Before an interview, prepare several real examples that cover different competencies, such as:
- Fault-finding
- Safe working
- Teamwork
- Quality
- Planning
- Leadership
- Responding to change
- Learning from a mistake
Practise explaining each example using Situation → Responsibility → Safety → Action → Result.
Do not memorise every word. Understand the example well enough to respond naturally when the interviewer asks follow-up questions.
Energy Recruitment Hub’s Interview Practice feature helps energy and engineering professionals practise role-specific questions and identify where their answers need clearer evidence, stronger technical reasoning or more detail about their personal contribution.
The goal is not to produce the longest answer. It is to provide enough relevant evidence for the interviewer to understand how you work.
