Your question is Testing Complex Backend APIs. 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).
Describe your approach to testing for complex backend APIs or cloud-based frameworks.
Explain how you would structure the test strategy, select test levels, manage data and dependencies, validate asynchronous behavior, and keep the suite reliable in CI. Include how you would test failures, security boundaries, compatibility, observability, and deployment smoke checks.
