easyJet Software Engineer interview questions & guide 2026

The following questions reflect patterns observed in our recent hiring cycles. While the exact questions you encounter may vary based on your specific team or seniority, these examples illustrate the core competencies and technical depth we assess.

Technical and Domain Expertise

These questions test your foundational engineering knowledge and your ability to apply technical concepts to real-world scenarios.

• Explain how you would approach optimizing a service experiencing high latency under load.
• What are the trade-offs between monolithic and microservices architectures in an airline context?

Preparation at easyJet is about demonstrating both your technical proficiency and your alignment with our operational values. Approach your preparation as an engineer who understands that code is a tool for solving business problems.

Technical Competency – We evaluate your depth of knowledge in your primary language and your understanding of engineering best practices. Be prepared to discuss your past projects, the architectural choices you made, and how you would improve those designs today.

Systemic Thinking – We look for candidates who can see the bigger picture. You should be able to articulate how your code interacts with the wider infrastructure and how it contributes to the overall stability and performance of our platforms.

Communication and Collaboration – Engineering at easyJet is a team sport. We value candidates who can articulate their thought process clearly, listen to feedback, and work constructively with product managers and other engineers.

The easyJet recruitment process is designed to be comprehensive yet professional. We typically begin with an initial screening to gauge your background and motivation, followed by technical assessments that may include virtual interviews or, for certain roles, an assessment center day. Our goal is to provide a smooth experience where you have the opportunity to showcase your skills across both technical and behavioral dimensions.

This visual timeline illustrates the typical progression from initial screening to final assessment. Use this to pace your preparation, ensuring you have enough time to review both your technical fundamentals and your behavioral stories before the assessment center or final round. Note that while the process is structured, the specific number of technical rounds can vary by team seniority and location.

Architectural Design

We value engineers who can design for scale and reliability. You will be evaluated on your ability to make trade-offs between availability, consistency, and performance.

Be ready to go over:

• Designing for high availability and disaster recovery.
• Understanding the implications of distributed systems and network latency.

As a Software Engineer, you will be responsible for the full software development lifecycle. You will write high-quality, maintainable code, participate in peer code reviews, and contribute to the architectural evolution of our systems. You will work closely with product owners to refine requirements and with operations teams to ensure seamless deployment and monitoring.

Your day-to-day will often involve tackling technical debt, scaling existing services to meet the demands of our growing customer base, and exploring new technologies that can improve our operational efficiency. Success in this role requires a proactive mindset—you are expected to identify potential issues before they impact the user and to suggest improvements that enhance our development velocity.

We seek engineers who bring a mix of technical rigor and a collaborative spirit. While your specific tech stack experience is important, your ability to learn and adapt is equally valued.

• Must-have skills: Proficiency in at least one major programming language (e.g., Java, C#, Python, or Go), experience with cloud platforms, and a strong understanding of RESTful APIs.
• Nice-to-have skills: Experience with containerization (Docker, Kubernetes), CI/CD pipelines, and familiarity with event-driven architectures.
• Experience level: We value a track record of delivering production-grade software and a clear understanding of how to work within an agile, cross-functional team environment.

Q: How long does the hiring process typically take? The timeline varies, but from initial contact to a final decision, it generally spans several weeks. We strive to maintain transparent communication throughout the process.

Q: Is it possible to work remotely? easyJet supports hybrid working models; specific expectations regarding office presence depend on the team and the location of the hub you are applying to.

Q: What differentiates a successful candidate? Successful candidates demonstrate a combination of technical depth, a pragmatic approach to problem-solving, and a clear passion for the aviation industry.

Q: How should I prepare for the group exercises? Focus on active listening and constructive collaboration. We evaluate how you contribute to the team's goals, rather than how you dominate the conversation.

• Be prepared to discuss your resume in detail: Interviewers will often ask you to deep-dive into the technical challenges you faced in your previous roles.
• Understand the "Why": Don't just explain what you did; explain why you chose a specific technology or approach over the alternatives.
• Stay calm under pressure: If you are unsure about a technical question, it is better to walk through your thought process than to guess.
• Ask meaningful questions: Use the end of your interviews to ask about team culture, technical challenges, or the roadmap for the department.

The Software Engineer position at easyJet is a unique opportunity to apply your skills to a high-stakes, high-impact environment. By focusing on your core technical fundamentals, refining your ability to explain complex architectural decisions, and demonstrating a collaborative mindset, you can significantly improve your chances of success.

We encourage you to review your past projects and prepare stories that highlight your problem-solving process. Remember that we are looking for engineers who are not only talented but also eager to contribute to our mission of making travel easy and affordable for everyone. Prepare thoroughly, stay confident, and good luck with your application.
