RELX Full Stack Engineer interview questions & guide 2026

The following questions reflect the patterns found in our data. While specific technical stacks may vary based on whether you are interviewing for a Java/React role or a PHP-focused position, the core themes remain consistent. Use these to identify the types of problems you will be asked to solve.

Technical and Stack-Specific Proficiency

These questions test your depth in your primary languages and your ability to explain architectural decisions.

• How do you manage state effectively in a complex React or Angular application?
• Can you explain the lifecycle of a Java request from the controller to the database?

Preparation at RELX should be as systematic as the software you will be building. Focus on demonstrating that you are not just a coder, but a thoughtful engineer who considers the long-term implications of your technical decisions.

Technical Competency – You must be prepared to demonstrate deep knowledge of your core language (e.g., Java, PHP) and framework (e.g., React, Angular). Beyond syntax, show that you understand the underlying patterns and best practices that ensure your code is maintainable and performant.

Architectural Thinking – RELX values engineers who can visualize how components interact. Be ready to discuss how you would structure an application from the database layer to the UI, considering factors like scalability, security, and ease of maintenance.

Communication and Collaboration – Working at RELX involves high levels of cross-functional cooperation. You will be evaluated on your ability to articulate your thought process clearly and work effectively with team members who may have different technical backgrounds.

Business Alignment – Understand that your code serves a professional user base. Be prepared to explain how your technical choices directly benefit the user experience and support the specific goals of the product you are working on.

The interview process at RELX is designed to be rigorous but fair, emphasizing a balanced assessment of your technical skills and your ability to fit into a collaborative, professional engineering environment. You should expect a series of discussions that move from initial screenings to more in-depth, role-specific technical evaluations.

The pace is generally steady, with a clear focus on the specific needs of the team you are applying to join. Throughout the process, interviewers look for a combination of deep technical expertise and a practical, problem-solving mindset. The philosophy is grounded in evaluating how you apply your skills to real-world scenarios rather than testing abstract academic knowledge.

The timeline above provides a visual map of the typical progression. Use this to pace your study, ensuring you have enough time to review both your language-specific fundamentals and your broader system design principles before reaching the later stages of the process.

Full Stack Depth

You are expected to be proficient across the entire stack. This means being able to discuss how front-end frameworks like React communicate with back-end services.

Be ready to go over:

• State Management – How you keep UI and data synchronized.
• API Design – Best practices for RESTful or GraphQL endpoints.

As a Full Stack Engineer, your primary responsibility is the development and maintenance of robust, scalable software solutions. You will be responsible for translating product requirements into technical specifications and delivering high-quality code. This involves working across the full development lifecycle, from initial design and development to testing, deployment, and ongoing support.

Collaboration is a daily requirement. You will work closely with product managers, UX designers, and other engineers to ensure that the software not only functions correctly but also meets the specific needs of RELX customers. You will often be involved in refining requirements, participating in sprint planning, and contributing to the architectural evolution of the systems you support.

A strong candidate for this role possesses a blend of hands-on coding ability and an understanding of enterprise-level software systems.

• Must-have skills: Proficiency in Java or PHP, and modern front-end frameworks like React or Angular. A strong grasp of SQL and database design is also essential.
• Nice-to-have skills: Experience with cloud infrastructure (e.g., AWS), containerization (e.g., Docker), and experience working in an Agile environment.
• Experience level: Most roles are targeted at mid-level or senior engineers who have demonstrated success in delivering complex web applications.

Q: How long does the hiring process usually take? A: While it varies by team, you should generally expect a process that spans a few weeks from the initial screen to a final decision. It is designed to be thorough but efficient.

Q: Is the technical assessment purely theoretical or practical? A: It is highly practical. You will be expected to discuss real-world scenarios and demonstrate how you solve problems you would encounter on the job at RELX.

Q: Does RELX value specific certifications? A: While technical depth is critical, RELX prioritizes proven experience and the ability to solve complex problems over certifications. Focus your preparation on your project portfolio and your ability to explain your past work.

• Focus on the 'Why': When discussing a technical choice, don't just say what you did; explain why you chose that approach over alternatives.
• Be ready for legacy code: At a company with the history and scale of RELX, you will often encounter existing codebases. Show that you are comfortable reading and improving older code.
• Communicate your process: During technical exercises, talk through your thought process out loud. Interviewers care as much about how you arrive at a solution as the solution itself.

The Full Stack Engineer role at RELX is a significant opportunity to work on software that powers global information solutions. By focusing on your core technical skills, architectural thinking, and ability to collaborate, you can position yourself as a strong candidate. Remember that your interviewers are looking for a teammate who can handle complexity and contribute to the long-term success of the product.
