Endava QA Automation Engineer interview questions & guide 2026

The following questions reflect patterns from recent interview experiences. While exact phrasing varies by project and team, the core themes remain consistent: foundational technical knowledge, practical problem-solving, and professional alignment.

Technical Foundations & Programming

These questions test your mastery of the languages and principles required to build reliable automation scripts.

• What are the core OOP principles, and how do you apply them in test automation?
• Can you explain how you utilize Java Collections in your framework?

Preparation at Endava requires a balanced approach. You must demonstrate both the technical rigor to write clean code and the analytical mindset to design comprehensive testing strategies.

Role-related Knowledge – You must be fluent in your primary automation language (typically Java) and understand how it integrates with testing frameworks. Interviewers evaluate your ability to write readable, maintainable code rather than just functional scripts.

Problem-solving Ability – You will be presented with scenarios that require logical thinking, such as debugging a failing test or optimizing a slow suite. Focus on explaining your thought process clearly, as the "how" is often as important as the final answer.

Communication & Culture Fit – Endava values collaborative professionals. Be prepared to discuss how you handle feedback, communicate technical risks to stakeholders, and contribute to a positive team environment.

The interview process at Endava is generally structured, fast-paced, and highly professional. Most candidates experience a multi-stage journey that moves from initial screening to in-depth technical assessments. You should expect a mix of HR-led discussions to assess your profile and cultural fit, followed by one or more technical rounds that may involve live coding, theoretical discussions, or take-home assignments.

The process is designed to be efficient, often moving from a screen to a final decision within a few weeks. The focus is on finding candidates who can hit the ground running, so expect the technical rounds to be grounded in real-world scenarios rather than abstract puzzles.

The timeline above highlights the typical progression from initial screening to final technical evaluation. Use this to pace your study; prioritize your technical fundamentals (like Java and SQL) early, and reserve time for practicing your responses to behavioral questions and your narrative regarding your career trajectory.

Technical & Coding Proficiency

This is the cornerstone of your evaluation. You are expected to demonstrate proficiency in Java core concepts and automation best practices.

Be ready to go over:

• OOP Principles – Encapsulation, inheritance, polymorphism, and abstraction.
• Data Structures – Efficient use of lists, maps, and sets in your test frameworks.

As a QA Automation Engineer, your daily routine revolves around the continuous improvement of the testing lifecycle. You will spend significant time writing and executing automated test scripts, maintaining existing frameworks to ensure they remain compatible with evolving codebases, and conducting thorough data validation using SQL.

Beyond coding, you will collaborate heavily with developers and product owners to define acceptance criteria for new features. This requires a proactive stance on quality; you aren't just finding bugs, but preventing them by ensuring that requirements are testable and that automated coverage is planned from the earliest stages of the sprint.

A competitive candidate at Endava possesses a blend of strong technical execution and a proactive mindset toward software quality.

• Must-have skills: Solid experience with Java, deep understanding of QA automation frameworks, and proficiency in writing complex SQL queries.
• Nice-to-have skills: Experience with CI/CD pipelines (e.g., Jenkins), containerization (Docker), and cloud environments.
• Experience level: A strong command of automation best practices is essential, typically paired with a demonstrated history of working in agile, team-oriented environments.

Q: How long does the interview process typically take? The process is known for being relatively fast, often spanning just a few weeks from the initial contact to a final decision.

Q: Should I expect a take-home test? It is common for candidates to encounter a technical assessment, which may be an online test or a take-home assignment, early in the process.

Q: What differentiates successful candidates? Successful candidates are those who balance technical expertise with a collaborative, communicative attitude—someone who can explain their code as clearly as they can write it.

Q: Is knowledge of Java mandatory? Given the prevalence of Java in Endava's tech stack, being comfortable with Java Core concepts is highly recommended for this role.

• Articulate your process: When solving coding tasks, talk through your logic out loud. Interviewers are looking for your problem-solving methodology, not just the final syntax.
• Know your resume: Be prepared to discuss every project you list, specifically focusing on the tools you used and the impact your automation had on the project.
• Prepare for SQL: Don't neglect your database skills; being able to write clean, efficient queries is a common requirement in technical rounds.
• Ask meaningful questions: Use the final stage of the interview to ask about the team’s testing strategy or the specific challenges they are solving; it demonstrates genuine interest.

The QA Automation Engineer role at Endava is an opportunity to join a global team that prioritizes technical excellence and strategic quality assurance. By focusing on your core Java skills, mastering SQL queries, and preparing to discuss your approach to automation, you will be well-positioned to succeed throughout the interview process.
