Explain the Test Pyramid and how it guides your strategy.
Tests your grasp of balanced automated testing. Define the pyramid's layers (Unit, Service, UI), explain trade-offs like speed and cost, then apply it to a new service. A red flag is describing the layers without explaining the 'why' behind the shape.
This tests your practical understanding of building a balanced, automated testing portfolio, not just reciting a definition. A strong answer defines the three layers (Unit, Service/Integration, UI), explains why the base is wide (fast, cheap unit tests) and the top is narrow (slow, brittle UI tests), and applies this to a new feature. The red flag is describing the layers without connecting them to cost, speed, and reliability, or failing to explain how a high-level test failure implies a missing unit test.
