Endava Mobile Engineer interview questions & guide 2026

Our interview process is designed to uncover your technical depth and your ability to apply core concepts in a practical setting. While questions are tailored to your specific experience level and the project needs, you should expect a blend of language-specific technical knowledge and foundational computer science principles.

Technical Foundations

These questions test your mastery of your chosen language (Swift/Kotlin) and your understanding of fundamental programming paradigms.

• What are optionals, and how do you define them?
• What is Kotlin, and what are the key differences between Java and Kotlin?

Preparation at Endava should be focused on articulating not just what you know, but how you think. We look for engineers who can bridge the gap between technical implementation and business requirements.

Technical Competency – You must demonstrate a strong grasp of your primary language (Swift or Kotlin) and the underlying mobile ecosystem. Be prepared to explain the "why" behind your code choices, such as why you chose a specific design pattern or memory management strategy.

Problem-Solving Approach – We value candidates who can break down complex requirements into manageable tasks. During your interview, walk the interviewer through your thought process; showing your logic is just as important as arriving at the correct technical answer.

Adaptability and Communication – As a consultant-led organization, Endava prioritizes clear communication. You should be able to explain technical concepts to non-technical stakeholders and demonstrate how you contribute positively to a team dynamic.

The Endava interview process is structured to be transparent, efficient, and respectful of your time. Candidates typically begin with an initial technical assessment or screening to establish a baseline of core knowledge. Following a successful evaluation, you will participate in a structured interview that combines technical deep-dives with discussions about your experience and cultural alignment.

We prioritize a two-way dialogue. Our goal is not only to evaluate your skills but to provide you with a clear picture of what it is like to work at Endava. You will interact with both technical leads and HR representatives, ensuring that we assess both your professional growth potential and your fit within our collaborative, agile environment.

This timeline illustrates the progression from your initial technical assessment to the final interview stage. Candidates should use this flow to manage their preparation energy, ensuring they brush up on language-specific syntax early while reserving mental capacity for the behavioral and situational questions that occur later in the process.

Mobile Development Proficiency

We evaluate your ability to write clean, maintainable code. You should be comfortable discussing platform-specific nuances and the lifecycle of mobile components.

Be ready to go over:

• Memory Management – Understanding retain cycles and garbage collection.
• Concurrency – How you handle background tasks without blocking the UI.

As a Mobile Engineer, your day-to-day work involves translating high-level product requirements into functional, high-quality mobile features. You will work closely with designers to ensure pixel-perfect implementation and with backend engineers to define efficient API contracts.

A significant portion of your time will be spent in code reviews, where you will both receive and provide feedback to maintain high project standards. You will also participate in daily stand-ups and sprint planning sessions, where you will estimate tasks and identify potential blockers early. Your ability to communicate these blockers effectively is essential for keeping our projects on track.

We look for engineers who are eager to learn and ready to contribute to complex projects immediately. While we value experience, we prioritize technical aptitude and the ability to work in a team.

• Must-have skills: Proficient in Swift (for iOS) or Kotlin (for Android), solid understanding of OOP, and practical experience with Git.
• Experience level: We value a mix of academic background and hands-on project experience. Being able to discuss your past projects in detail is a significant advantage.
• Soft skills: Strong interpersonal skills, a proactive attitude toward learning, and the ability to thrive in an agile, collaborative environment.

Q: How long does the entire process usually take? The timeline can vary based on project needs, but we strive for a fast turnaround. From your initial assessment to the final decision, most candidates move through the process within a few weeks.

Q: What is the most common reason candidates don't pass? Candidates often struggle when they can write code but cannot explain the underlying principles or the trade-offs they made. Being able to explain "why" you made a technical decision is crucial.

Q: Is there a specific focus on algorithms? While we focus heavily on practical application, having a solid grasp of basic data structures and algorithmic complexity is important for solving system-level problems.

• Show your work: If asked a technical question, don't just give a one-word answer. Explain the trade-offs of the solution you chose.
• Stay curious: If you don't know the answer to a specific technical question, explain how you would go about finding the answer. We value problem-solving skills over encyclopedic knowledge.
• Be prepared for behavioral questions: We want to understand how you handle conflict and collaboration. Use the STAR method (Situation, Task, Action, Result) to keep your answers structured.

Embarking on a career as a Mobile Engineer at Endava offers the chance to work on impactful projects that challenge your technical boundaries. By focusing on your core language proficiency, understanding your past project trade-offs, and demonstrating a collaborative mindset, you will be well-positioned to succeed. Remember that your interviewers are looking for a partner in engineering, so approach the conversation with confidence and curiosity.
