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.
Q3
Describe your approach to writing effective test cases. What makes a test case maintainable, and how do you handle test data management in a large-scale application?
Why they ask this:* They're assessing your foundational QA knowledge, attention to detail, and understanding of scalability challenges in test automation.
Q4
What's your experience with performance and load testing? Walk me through a scenario where you identified a performance bottleneck and how you communicated findings to the development team.
