Centrica Interview: Process, Questions & How to Pass

Centrica's Typical Interview Process at a Glance

Centrica — the energy services group behind British Gas — typically runs a multi-stage recruitment process. While exact stages vary by role and level, candidates for graduate, professional, and corporate positions commonly move through an online application and screening stage, one or more psychometric assessments, a video or telephone interview, and a final-stage interview or assessment centre.

Understanding the shape of the process before you start lets you pace your preparation rather than cramming everything the night before. Each stage is designed to filter for different things: the assessments test cognitive fit, while the interviews dig into your values, behaviours, and technical knowledge.

• Stage 1: Online application and CV/cover letter screening
• Stage 2: Psychometric or situational judgement tests
• Stage 3: Video or telephone interview (competency-based)
• Stage 4: Final interview or assessment centre (may include a case study, group exercise, or presentation)
• Timeline varies — graduate schemes often follow a structured annual cycle; experienced hires can move faster

What Centrica Looks for: Values and Competencies

Centrica has publicly stated a focus on purpose-led business — delivering sustainable energy and services to customers while operating responsibly. In practice, interviewers typically probe for competencies such as customer focus, commercial awareness, collaboration, and continuous improvement. For technical roles, problem-solving and analytical thinking feature prominently.

Before your interview, read Centrica's published purpose and values on their corporate website. Note specific language they use — interviewers often reward candidates who mirror the organisation's own framing rather than speaking in generic corporate terms.

• Customer focus: genuine commitment to customer outcomes, not just process compliance
• Commercial awareness: understanding of the energy sector, regulation, and competitive landscape
• Collaboration: evidence of working across teams or functions to achieve a shared goal
• Adaptability: ability to work through change in a fast-moving regulated industry
• Integrity: alignment with responsible, ethical business practice

Common Centrica Interview Questions (and What They're Really Testing)

Competency interviews at Centrica — as with most large UK employers — are heavily behavioural. You will be asked to describe past experiences rather than hypothetical scenarios. Below are representative question types drawn from the competencies Centrica publicly emphasises. These are illustrative; your actual questions may differ.

Alongside behavioural questions, expect some motivational questions ('Why Centrica?', 'Why this role?') and, for commercial or technical roles, sector-knowledge questions such as 'What challenges do you think the UK energy industry faces over the next five years?'.

• 'Tell me about a time you delivered an exceptional experience for a customer or stakeholder.'
• 'Describe a situation where you had to adapt quickly to a significant change.'
• 'Give me an example of when you identified an improvement in a process and drove it forward.'
• 'Tell me about a time you worked with a diverse team to achieve a difficult goal.'
• 'How do you stay informed about developments in the energy sector?'

How to Use STAR to Structure Standout Answers

The STAR method — Situation, Task, Action, Result — gives your answers a clear narrative arc that interviewers can score against competency frameworks. The most common mistake candidates make is spending too long on the Situation and skipping the Result. Aim for roughly 10% Situation, 10% Task, 60% Action, and 20% Result.

Here is an example answer to the question: 'Tell me about a time you delivered an exceptional experience for a customer or stakeholder.'

• Situation: 'I was working as an account coordinator at a utilities consultancy when a long-standing client flagged that their monthly billing reports were consistently arriving late, causing them to miss internal deadlines.'
• Task: 'My manager asked me to investigate the root cause and propose a fix within a fortnight.'
• Action: 'I mapped the entire reporting workflow, identified that the bottleneck sat with a manual data-export step, and built a semi-automated template in Excel that cut preparation time by about 40%. I also set up a shared calendar reminder so the team knew the send deadline five days in advance.'
• Result: 'Reports were delivered on time for every subsequent month of my tenure. The client mentioned the improvement unprompted in their annual review, and we retained the contract — which was worth roughly £80,000 a year to the business.'

Preparing for a Video or One-Way Interview Stage

Some Centrica roles include a pre-recorded or one-way video interview — a format where you record answers to set questions within a time limit, with no live interviewer present. If you have not done this before, it can feel unnatural and the time pressure can cause strong candidates to underperform.

The single best way to prepare is to practise on camera under realistic time constraints. ScreenReady is built specifically for this: it simulates timed, one-way video interviews and gives you AI feedback on your answer content and delivery, so you can identify weak spots before the real thing. At minimum, record yourself answering three to five STAR questions, watch them back, and note where your answers lose focus or run over time.

• Check your lighting (face the light source, do not sit with a window behind you)
• Use a plain or tidy background — remove distractions
• Look into the camera lens, not at your own image on screen
• Speak at a measured pace; nerves tend to make people rush
• Have your STAR notes visible just off-screen as a prompt, not a script

Assessment Centre Tips for Centrica

If you reach an assessment centre, you may encounter a combination of group exercises, a case study or in-tray exercise, a presentation, and a final competency interview. Assessment centres assess not just what you produce but how you behave under pressure and alongside other candidates.

In group exercises, interviewers are watching for constructive contribution — not dominance. Listen actively, build on others' points, and bring quieter participants into the discussion. In case studies, structure your analysis clearly: state your assumptions, work through the data logically, and land on a clear recommendation with supporting evidence. Do not treat the right answer as the only goal; assessors want to see your thinking process.

• Read any pre-read materials thoroughly the evening before
• Prepare a two-minute overview of Centrica's business in case you are asked to present on it
• Bring concrete examples from your preparation to the final interview — do not improvise them on the day
• Ask one or two genuinely curious questions at the end; avoid questions whose answers are on the first page of the website

Final Preparation Checklist

Use the week before your interview to work through the checklist below. Good preparation is not about memorising scripts — it is about having enough material ready that you can respond naturally under pressure.

• ✓ Read Centrica's latest annual report summary and any recent news (energy policy, acquisitions, sustainability targets)
• ✓ Prepare five to seven STAR stories that cover the core competencies — customer focus, collaboration, adaptability, improvement, commercial awareness
• ✓ Practise answering out loud, on camera, within two-minute limits
• ✓ Prepare a concise 'Why Centrica?' answer that references specific strategic initiatives, not just the brand name
• ✓ Research your interviewer on LinkedIn if their name is provided — note any shared context
• ✓ Prepare two or three thoughtful questions to ask at the close of the interview
• ✓ Confirm logistics: dial-in link or address, ID requirements, and time zone if remote
