eToro QA Automation Engineer interview questions & guide 2026

The questions below represent common patterns observed in eToro interviews. While the specific technical tasks may evolve, the core themes remain focused on your practical application of automation tools and your problem-solving methodology.

Technical and Domain Expertise

These questions test your proficiency with the core stack used at eToro, specifically focusing on C#, Selenium, and API testing.

• Can you provide examples of how you have implemented Selenium in your previous projects?
• How do you handle authentication and token management when automating API testing?

Preparation at eToro requires a balance of hands-on coding readiness and the ability to articulate your testing philosophy. You should be prepared to discuss your past technical decisions in depth, justifying why you chose specific tools or patterns.

Technical Proficiency – You must be comfortable writing and explaining C# code. Interviewers will look for clean, modular, and efficient code during your technical review and home assignment.

Analytical Thinking – Your ability to decompose a problem is as important as the code itself. When answering, focus on how you structure your automated tests to be scalable and resilient to change.

Collaboration and Communication – eToro values engineers who can bridge the gap between QA and development. Be prepared to explain how you advocate for quality and how you handle constructive feedback from developers.

The interview process at eToro is designed to be direct, transparent, and professional. It typically begins with an initial screening to gauge your background and cultural alignment, followed by a practical home assignment that serves as the foundation for subsequent technical discussions.

You can expect to interact with both QA and Development leadership. The process focuses on your ability to apply your skills to real-world scenarios, such as API interactions and automated test development. The timeline is generally efficient, with interviewers maintaining a high level of transparency regarding expectations and compensation.

This timeline illustrates the progression from initial contact through technical validation. Use this structure to allocate your preparation time, ensuring you prioritize the home assignment as it acts as the centerpiece for your technical interviews.

Automation Framework Design

The team evaluates your ability to build frameworks that are not only functional but also scalable and easy to maintain. You should be ready to discuss how you structure your test projects, manage dependencies, and handle test data.

Be ready to go over:

• Page Object Model (POM) – How you organize UI tests.
• Data-driven testing – Techniques for running tests with various input sets.

As a QA Automation Engineer, your day-to-day will revolve around increasing the coverage and efficiency of the regression suite. You will be responsible for translating manual test cases into robust automated scripts, ensuring that new features do not introduce regressions into the core trading platform.

Collaboration is a daily requirement. You will work alongside developers to review code, participate in design discussions to ensure testability, and investigate bugs reported by the community or internal stakeholders. You are not just a tester; you are a quality advocate who influences the development process to prevent issues before they reach production.

Q: How difficult is the technical home assignment? A: The assignment is designed to be completed within a few hours and tests your ability to handle real-world tasks like API interaction. Focus on writing clean, readable code rather than over-engineering the solution.

Q: What differentiates a successful candidate? A: Successful candidates demonstrate not just "how" they wrote code, but "why." They show an understanding of how their automation impacts the overall development lifecycle and team velocity.

Q: Is there a focus on specific testing methodologies? A: Yes, there is a strong preference for automated, repeatable tests. You should be prepared to discuss the balance between UI and API testing in your previous roles.

• Explain your logic: When discussing your home assignment, explain the trade-offs you made. If you chose a specific library or pattern, be ready to justify it.
• Be ready for code reviews: Treat your interviewers as you would your peers. Be open to discussing potential improvements to the code you submit.
• Focus on the "why": When asked about past problems, focus on the process you used to find the root cause, rather than just the final fix.
