GetYourGuide Backend Engineer interview questions & guide 2026

The following questions represent patterns observed in our hiring process. They are intended to illustrate the types of challenges you will encounter rather than serve as a memorization list. Prepare to articulate your thought process clearly, as our interviewers value your reasoning as much as the final solution.

Technical Refactoring and Implementation

These questions assess your ability to clean up existing code, apply design patterns, and maintain high standards of code quality in a production environment.

• Refactor this poorly written REST service to improve readability and performance.
• How would you approach modifying a legacy codebase while ensuring zero downtime?

Success at GetYourGuide requires a balance of technical precision and soft-skill maturity. We look for engineers who are not only capable of writing clean code but who also thrive in a collaborative, fast-paced environment.

Technical Competence – We expect proficiency in your primary language and a deep understanding of software engineering fundamentals. You should be able to demonstrate mastery of SOLID principles, OOP, and effective code refactoring techniques.

Problem-Solving Approach – We evaluate how you break down ambiguous tasks. When faced with a coding challenge, communicate your assumptions, explore edge cases, and justify your design choices before diving into implementation.

Ownership and Leadership – We value engineers who take responsibility for their code and their team's success. Show us how you have proactively identified problems, implemented non-technical processes to improve efficiency, or mentored peers.

Cultural Fit – We look for individuals who are curious about our product and mission. Be ready to discuss how your work aligns with our goals and how you handle the realities of working in a large-scale, evolving organization.

The GetYourGuide interview process is designed to be efficient, transparent, and collaborative. We prioritize getting to know you as both an engineer and a teammate. While the exact structure can vary by team, the process generally moves from initial screenings to deep-dive technical sessions, concluding with management and leadership touchpoints. We value candidates who are communicative and open throughout these stages.

Expect a rigorous but fair evaluation. We emphasize real-world scenarios—such as refactoring existing services or discussing past project challenges—over abstract riddles. Our interviewers aim to create a dialogue where you can showcase your ability to think critically in a team context.

This timeline outlines the typical flow from your initial recruiter conversation to final leadership interviews. Use this to pace your preparation; ensure you have reviewed your past projects and are ready to discuss your technical decision-making process before reaching the final stages.

Technical Depth and Refactoring

We focus on your ability to work with real code. You will be asked to handle messy, legacy-style services, requiring you to apply SOLID principles and design patterns to improve maintainability. Strong candidates write clean, testable code and can explain their refactoring choices.

Be ready to go over:

• Code Maintainability – Why readability is as important as functionality.
• Design Patterns – When and how to apply patterns like Factory or Adapter.

As a Backend Engineer, your primary objective is to build reliable, high-performance services that support our supply and marketplace operations. You will spend your day-to-day writing and reviewing code, participating in architectural discussions, and collaborating with cross-functional partners to ship features that enhance the traveler experience.

You will often find yourself working with legacy systems that require thoughtful refactoring. This involves analyzing current performance bottlenecks, identifying areas for improvement, and implementing changes that align with our long-term technical roadmap. You are expected to be a force multiplier, contributing not just through code, but through documentation, code reviews, and active participation in team planning.

We are looking for engineers who are pragmatic, communicative, and technically sound. While specific requirements may vary by team, the following are core expectations for our Backend Engineers.

Must-have skills

• Strong proficiency in modern backend languages (e.g., Java, PHP).
• Deep understanding of OOP and SOLID principles.
• Experience with REST API design and maintenance.
• Ability to write clean, testable code in a collaborative, pair-programming environment.

Nice-to-have skills

• Experience working with high-traffic distributed systems.
• Familiarity with A/B testing frameworks and data-driven development.
• Prior experience with cloud infrastructure and CI/CD pipelines.

Q: How long should I spend preparing for the coding interview? A: Focus on quality over quantity. Instead of memorizing algorithms, practice refactoring messy code snippets. Aim to be comfortable explaining your thought process out loud while you code.

Q: Is there a specific focus on legacy code? A: Yes, we often ask candidates to refactor existing code. This is because much of our work involves evolving established services. Be prepared to discuss how you would improve a service without introducing regressions.

Q: How does the interview process handle different seniority levels? A: While the core stages remain consistent, the depth of questions regarding system design, leadership, and ownership will scale with the seniority of the role you are applying for.

Q: What is the best way to demonstrate culture fit? A: Be honest and sincere. We value candidates who are passionate about the travel industry and who can clearly articulate why they want to work at GetYourGuide specifically.

• Think out loud: Our interviewers are interested in your process. Even if you are stuck, verbalizing your thoughts helps the interviewer understand your problem-solving logic.
• Ask questions: At the end of your interviews, use your time to ask thoughtful questions about our technology stack, team culture, or product challenges.
• Be ready for legacy: Do not be intimidated by discussions about legacy PHP or complex refactoring tasks. Embrace them as opportunities to show your engineering maturity.
• Prepare your stories: Use the STAR method (Situation, Task, Action, Result) to structure your answers for behavioral questions.

A Backend Engineer role at GetYourGuide offers the unique opportunity to solve complex, high-scale engineering challenges that directly impact how people explore the world. By focusing your preparation on code quality, system design, and collaborative problem-solving, you can confidently showcase your ability to contribute to our mission.
