Before you interview
Interview tips for Competition Specialist
Competition Specialist interviews in the UK typically involve behaviour and strengths-based interviews aligned to government frameworks. Come prepared with policy impact, stakeholder management, or service delivery improvements that demonstrate your capability — vague answers about "teamwork" or "problem-solving" won't cut it. Be ready to discuss your experience with Competition case management systems, Data analysis software, Microsoft Office — interviewers will probe how you've applied these in practice, not just whether you've heard of them.
Research the organisation's public sector & government approach before you walk in. Understand their recent projects, market position, and what challenges they're likely facing. The strongest candidates connect their experience directly to the employer's priorities rather than reciting a rehearsed pitch.
For behavioural questions, structure your answers around a specific situation, what you did, and the measurable outcome. Be specific about numbers, timelines, and outcomes — "increased efficiency by 22% over six months" lands better than "improved the process."

Frequently asked questions
What's the difference between competition law and antitrust law?
Same thing—different terminology. "Antitrust" is US term; "competition law" is UK and EU term. Both address monopolistic behaviour, cartels, mergers that harm competition, and abuse of dominant position. UK competition law is based on similar principles to EU law (retained post-Brexit). Key statutes: Competition Act 1998 (cartels, abuse), Enterprise Act 2002 (merger control). Understanding both UK and international frameworks matters for specialists.
How do I move into competition law from general law or economics?
Postgraduate qualification in competition law is valuable—universities offer LLMs in competition law or economics. Some CMA trainee schemes accept lawyers and economists without competition background; they provide training. If you're economist, legal understanding helps but not essential. Law firms and in-house teams often recruit and train. Start with entry-level role (paralegal, case officer) then progress. Sector knowledge (tech, utilities, healthcare) is valuable; you learn competition law on job.
What sectors have significant competition issues?
Tech and digital (market dominance, data, mergers—Google, Amazon, Meta), utilities (essential infrastructure—energy, water), telecommunications (Ofcom oversight), pharmaceuticals (patent and generic competition), aviation, banking and financial services. COVID-19 and cost-of-living crisis intensified scrutiny of essential sectors. Specialist expertise in high-value sectors (tech, energy, pharma) commands premium salaries and opportunities.
What's the typical career path in competition?
Competition Officer → Specialist → Manager or partner (in private practice). Some stay in regulator roles; others move to private practice for higher pay. In-house competition teams also option (corporate legal). Many practitioners move between regulator, private practice, and in-house throughout careers. Sector moves common—expertise in utilities sector, then tech sector, for example. Specialisation and expert reputation valuable throughout career.
How important is being a qualified lawyer for competition work?
Not essential, particularly in regulator roles. CMA and sector regulators employ economists, business analysts, and non-lawyer specialists. Qualified lawyer status valuable for partner roles in private practice and some senior positions. If you're economist or data analyst, you can have successful competition career without law qualification. However, understanding law and legal frameworks is essential. Training available; many competition teams have strong learning culture.
What's the impact of Brexit on UK competition law?
UK retained and adapted EU competition framework post-Brexit. CMA now enforces UK law independently (previously coordinated with EU). Differences emerging—UK can be faster, more pragmatic in some areas. However, alignment with international standards (US, EU) matters for global businesses. Competition specialists navigating UK-EU divergence are valuable. Post-Brexit, UK has more flexibility in merger control, making specialist knowledge increasingly important for advisors.
