How do you fix an inverted test pyramid?
This tests your ability to create a pragmatic, multi-sprint plan to improve test suite health. A good answer involves analyzing tests, getting buy-in, then incrementally adding unit/integration tests while refactoring old E2E tests.
This assesses your strategic thinking and ability to lead a technical initiative with real-world constraints. It's about how you'd pragmatically fix a bad test suite while still delivering features. A strong answer outlines a multi-sprint plan: analyze flakiness, secure team buy-in and capacity (e.g., 20%), enforce that new/changed code gets proper unit/integration tests, and systematically replace brittle E2E tests with faster integration tests. A major red flag is proposing to halt all feature development for a 'testing sprint'.
