RELX Software Engineer interview questions & guide 2026

The questions below are representative samples drawn from real reported interview experiences across various regions and seniority levels. While exact questions depend on your specific team and tech stack, they illustrate the core patterns you will encounter during your evaluation.

Technical and Language-Specific Questions

• Assess your command of core programming languages, frameworks, and modern development best practices.
• Write small Java programs or explain advanced concepts in Spring and Hibernate.
• Discuss object-oriented design principles and how you structure your unit tests following TDD principles.

Preparing effectively for a Software Engineer position at RELX requires a balanced focus on core technical mastery, rigorous problem-solving, and clear professional communication. You should review your fundamental computer science concepts while brushing up on the specific frameworks listed in your target team's tech stack.

Role-related knowledge – This criterion measures your practical and theoretical mastery of software engineering, including your chosen programming language, cloud technologies like AWS, and database management. Interviewers evaluate this through technical phone screens, deep-dive discussions, and live coding exercises. You can demonstrate strength here by explaining your design choices clearly, writing clean unit tests, and showing deep familiarity with your primary tech stack.

Problem-solving ability – This encompasses how you approach ambiguous technical challenges, break down complex requirements, and arrive at optimal solutions. Interviewers look closely at your thought process during coding tasks and architectural whiteboarding sessions rather than just your final answer. To excel, talk through your assumptions, consider edge cases proactively, and adapt quickly when given hints or constraints by your interviewers.

Leadership and collaboration – At RELX, engineering is a team sport that requires close coordination with product managers, QA specialists, and external stakeholders. Interviewers evaluate your interpersonal skills, conflict resolution abilities, and how you handle cross-functional feedback. You can prove your strength here by sharing concrete examples of how you mentored junior developers, partnered with QA to squash critical bugs, or communicated complex technical risks to non-technical partners.

Culture fit and values – This evaluates your alignment with the company's collaborative ethos, professionalism, and dedication to delivering high-quality customer solutions. Interviewers assess this during behavioral rounds and final panel interviews where personality and cultural alignment take center stage. Demonstrate your enthusiasm for continuous learning, your respect for peer feedback, and your commitment to building reliable software products.

The interview journey for a Software Engineer at RELX typically begins with an initial resume screening by talent acquisition, followed by an online analytical or technical assessment. Once you pass these preliminary filters, you will advance through a series of technical phone screens with engineering managers and developers. These conversations focus on your past experience, core coding capabilities, and foundational knowledge in languages like Java, Python, or C#. Candidates who impress in the screening phases are invited to an intensive onsite or virtual loop that combines live coding challenges, system design whiteboarding, and comprehensive behavioral evaluations with cross-functional stakeholders.

Expect a rigorous evaluation pace where interviewers actively probe your thought processes, architectural decisions, and day-to-day engineering habits. The company values collaborative problem solvers who can articulate why they write specific code, not just how it works. While the process is thorough and occasionally multi-staged, it offers ample opportunity to interact with future peers and technical leads, giving you a clear window into the engineering culture.

The visual timeline above outlines the typical progression from initial application and screening through technical rounds and final panel interviews. Use this timeline to pace your preparation, ensuring you allocate sufficient time for both algorithmic coding practice and system design review. Keep in mind that specific stages can vary based on your geographic location, seniority level, and the specific engineering squad you are targeting.

Technical Competency and Coding

• This area evaluates your raw programming ability, fluency in your primary language, and adherence to clean code standards. Interviewers test this through live coding sessions, where you may be asked to write code in a shared environment or notepad without a compiler. Strong performance means writing well-structured, bug-resistant code while explaining your logic clearly.

Be ready to go over:

• Data structures and algorithms – Fundamental collections, sorting, searching, and time complexity analysis.
• Object-oriented programming – Inheritance, polymorphism, encapsulation, and design patterns.

As a Software Engineer at RELX, your primary responsibility is to design, develop, test, and maintain robust software solutions that power the company's vast network of information and analytics products. You will own features and system components through their entire lifecycle, from initial concept and architectural design to production deployment and ongoing monitoring. Your day-to-day work involves writing clean, maintainable code, optimizing database queries, and ensuring high availability across distributed cloud environments.

Collaboration is central to your daily routine. You will work side-by-side with product managers to translate customer requirements into technical specifications, partner with QA engineers to maintain rigorous testing standards, and collaborate with DevOps teams to streamline CI/CD pipelines. Whether you are modernizing legacy codebases or building brand-new AI-enabled search platforms, your focus remains squarely on delivering secure, scalable, and performant software that delights professional users across industries.

Meeting the bar for a Software Engineer at RELX requires a solid blend of technical prowess, professional experience, and strong interpersonal skills. The organization values engineers who are adaptable, detail-oriented, and capable of working effectively within global, cross-functional teams.

• Must-have technical skills – Proficiency in at least one core programming language (such as Java, Python, or C#), a strong foundation in data structures and algorithms, and hands-on experience with modern development tools like Git, Maven, and automated testing frameworks.
• Cloud and systems experience – Practical knowledge of cloud platforms, specifically AWS, along with experience designing RESTful APIs and working with relational or NoSQL databases.
• Experience level – A bachelor's or master's degree in Computer Science, Engineering, or a related technical discipline, paired with relevant commercial software engineering experience commensurate with the specific job level.
• Soft skills – Excellent verbal and written communication skills, a collaborative mindset when partnering with QA and product teams, and the ability to articulate complex technical concepts clearly.
• Nice-to-have skills – Prior experience with search engines and AI platforms, familiarity with containerization tools like Docker and Kubernetes, and a track record of mentoring junior engineers.

Q: How difficult is the interview process, and how much preparation time is typical? The interview process is moderately rigorous, combining technical screens, live coding, and system design evaluations. Most candidates benefit from dedicating 3 to 4 weeks of focused preparation, refreshing their data structures, practicing coding problems without an IDE compiler, and reviewing system architecture fundamentals.

Q: What differentiates successful candidates from those who are rejected? Successful candidates distinguish themselves not just by getting the right answer, but by how they communicate their reasoning. Interviewers look for engineers who articulate their assumptions, write clean unit tests, and demonstrate a collaborative, problem-solving attitude when given feedback.
