Walk me through how you would design a comprehensive test strategy for a microservices-based REST API. What types of testing would you prioritize, and how would you decide between automated and manual testing?
Why they ask this:* They want to assess your understanding of modern architecture, test planning methodology, and your ability to balance resource allocation across different testing types.
Q2
Explain your experience with CI/CD pipelines. How have you integrated automated tests into a pipeline, and what challenges did you encounter with test flakiness or execution time?
Why they ask this:* This evaluates your hands-on experience with DevOps practices, tool proficiency (Jenkins, GitLab CI, GitHub Actions), and your ability to solve real-world automation problems.

Q7
Share an example of when you had to collaborate closely with developers to resolve a disagreement about whether something was a bug or expected behavior. How did you handle the conflict and reach resolution?
Q8
How would you handle a situation where a developer pushes back on your bug report, claiming they can't reproduce the issue and questioning whether it's actually a defect?
Q9
What would you do if you inherited a legacy codebase with zero automated tests and were asked to improve quality within the next sprint?
