Your question is Structuring a Complex Test Suite. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain how you would structure a test suite for a complex application.
Describe how you would organize tests across unit, integration, API, UI, end-to-end, regression, and exploratory testing. Explain how you would prioritize coverage, manage test data and environments, integrate the suite into CI/CD, and balance execution speed with release confidence. Be prepared to discuss ownership, reporting, maintenance, and how your approach would change as the application and team grow.
