Sample interview questions
How would you design a maintainable Java-based automated testing framework for backend services?

I would use a layered structure that separates test data, API clients, assertions, configuration, and reporting. I would build reusable utilities around JUnit 5 and Spring test support, keep environment-specific configuration externalized, and ensure tests can run consistently in local and CI environments.

How do you decide which scenarios belong in API tests versus UI end-to-end tests?

I prioritize API tests for business rules, edge cases, integration contracts, and fast feedback because they are generally more stable and faster to execute. I reserve UI end-to-end tests for critical user journeys and frontend integration, keeping that suite focused to reduce flakiness and execution time.

What steps do you take when a regression test becomes flaky in CI?

I first collect logs, screenshots, traces, and timing data to identify whether the issue is test synchronization, environment instability, data dependency, or a product defect. I then remove arbitrary waits, improve deterministic setup and cleanup, use robust synchronization, and track the issue until the test is reliable rather than masking it with repeated retries.

How would you incorporate performance and chaos testing into a product team’s delivery process?

I would establish measurable service-level expectations, create repeatable load scenarios for critical workflows, and run them regularly in an environment representative of production. For chaos testing, I would introduce controlled failures such as unavailable dependencies or pod restarts, validate system resilience, and turn findings into reliability improvements and automated checks.

How do you collaborate with developers to improve requirements from a testability perspective?

I join refinement discussions early and ask for clear acceptance criteria, expected error behavior, observability needs, and test data requirements. I help identify risky paths and propose test hooks, stable identifiers, API contracts, and logging that make both automated verification and production troubleshooting easier.
