Topics Covered

-Automation framework design and maintainability trade-offs
-Layered testing strategy (unit, API, integration, UI, E2E)
-Mocking and service virtualization techniques
-Parallel execution, test stability, and flaky test quarantine
-Quality gates in CI/CD and release readiness criteria
-Defect prevention, triage workflows, and quality metrics

Difficulty Level

This is a senior-level SDET interview. Expect deep technical reasoning on test strategy and engineering quality, not only tool usage. Ask for specific examples where they improved pipeline reliability, reduced flakiness, or shifted tests to faster layers. Use follow-ups like 'What signals made that suite unreliable?' and 'How did you prove the change improved release confidence?' Strong candidates should discuss architecture, developer collaboration, and measurable quality outcomes.
