Testing Technical Depth and Automation Questions

Covers deep, practical expertise in software testing and test automation. Candidates should demonstrate mastery across types of testing including unit, integration, end to end, performance, security, and infrastructure testing, and show how these fit into the delivery lifecycle. Expect questions about designing automated test architectures, selecting frameworks and tools, test pyramids and trade offs, test data management, parallelization and scaling of test runs, flakiness mitigation, observability and reporting, and how testing interacts with deployment and CI CD pipelines. Be prepared to reason from first principles about testing problems, explain architectural decisions, and give concrete examples of diagnosing and solving complex testing challenges in production systems.
