The questions below represent the core areas tested during the Centrica interview process. While specific questions fluctuate based on the desk you are interviewing with, the focus remains on your ability to apply financial theory to real-world energy markets.

Finance & Accounting

Technical questions here test your fundamental understanding of pricing, valuation, and market instruments.

• Explain what a derivative is.
• How would you approach the valuation of a storage option in the gas market?

Preparation for Centrica requires a disciplined approach that balances technical mastery with a sharp, current perspective on commodity markets. You should treat your preparation like a desk-readiness exercise.

Technical Knowledge – Ensure you are comfortable with the basics of derivatives, option greeks (Delta, Gamma, Theta, Vega), and the specific mechanics of energy trading. You will be expected to apply these concepts to real-world scenarios rather than just reciting textbook definitions.

Commercial and Market Awareness – You must stay informed on global energy news, geopolitical events affecting supply chains, and macroeconomic trends. Being able to articulate a coherent view on current market moves is a major differentiator for successful candidates.

Problem-Solving Under Pressure – Many interviews involve live case studies or mental math questions designed to see how you think when the clock is ticking. Practice solving quantitative puzzles quickly and be prepared to explain your logic clearly to the interviewer.

Fit and Motivation – Centrica looks for candidates who are not just smart, but resilient and genuinely curious about the energy sector. Demonstrate your passion by discussing recent developments in the industry and how the firm’s specific business model aligns with your career goals.

The interview process at Centrica is designed to test your technical aptitude, your ability to handle pressure, and your cultural alignment with their trading teams. You should expect a rigorous sequence that typically begins with an HR screen followed by multiple rounds of technical interviews. The process often includes an online aptitude test, and for finalists, an assessment center that may feature a group exercise, a case study, and further interviews with senior traders.

The firm values efficiency, though candidates should be prepared for varying communication cadences throughout the process. The assessment center is often the most critical stage, as it provides a holistic view of how you work within a team and how you handle complex, time-sensitive tasks. Be ready for "on-the-spot" technical questions, especially those related to gas and power markets, as these are core to the firm’s operations.

The visual timeline above highlights the progression from initial screening to the final assessment center. Candidates should use this to pace their preparation, ensuring they are ready for technical deep-dives early on, while reserving energy for the more interactive group exercises and case studies that occur toward the end of the loop.

Market Knowledge & Trade Pitching

Your ability to speak intelligently about the energy landscape is non-negotiable. Interviewers want to see that you follow the markets daily.

Be ready to go over:

• Market Drivers – Factors influencing supply/demand in gas and power.
• Trade Rationale – The ability to construct a logical, data-backed pitch for a specific market move.

As a Sales and Trading Analyst, your primary responsibility is to provide the analytical backbone for the trading desk. You will monitor live market data, update pricing models, and help identify potential arbitrage or hedging opportunities. You will collaborate closely with traders to execute orders and ensure that all trades are properly logged and risks are identified in real-time.

Beyond execution, you will often be tasked with preparing daily market reports that synthesize news and price movements for senior leadership. You will work across teams, communicating with logistics, risk management, and compliance to ensure that trading activities remain within internal and regulatory guidelines. This role is about precision, speed, and the ability to turn raw data into actionable intelligence.

Successful candidates for the Sales and Trading Analyst role possess a strong quantitative foundation combined with a genuine interest in the energy sector.

• Must-have skills – Proficiency in Excel, strong mental math capabilities, a clear understanding of financial derivatives, and the ability to distill complex information into concise insights.
• Nice-to-have skills – Familiarity with Python or other programming languages for data analysis, previous internship experience in a trading or energy environment, and a working knowledge of commodity market structures.
• Soft skills – Exceptional communication skills, the ability to remain calm under pressure, and a collaborative mindset for working in a fast-paced team environment.

Q: How long should I spend preparing for the technical rounds? A: Dedicate at least 3–4 weeks to mastering the fundamentals of derivatives and energy markets. Focus on being able to explain "why" a market is moving, not just "what" is happening.

Q: What differentiates the top candidates? A: The best candidates show a "trader’s mindset"—they are curious, they have an opinion on the markets, and they can defend that opinion with logic and data.

Q: Is the culture at Centrica very competitive? A: It is a high-performance environment that rewards initiative and collaboration. You will be expected to contribute to the team’s goals immediately, so showing a strong work ethic is essential.

Q: What is the typical timeframe for the process? A: The process can take anywhere from a few weeks to over a month, depending on the stage of the recruiting cycle. Remain proactive in your communication.

• Structure your technical answers: When answering technical questions, state your answer first, then provide the logic, and finally conclude with the implication.
• Stay current: Read industry news every morning. You will be asked about current events, and "I haven't seen the news today" is a red flag.
• Practice mental math: Do not rely on calculators for simple arithmetic. You will be expected to perform these tasks on the fly during interviews.
• Be clear on your "Why": Have a compelling, personal reason for wanting to work in commodities and specifically at Centrica.
