What is a page object or component model in e2e testing?
Short interview answer
It's a wrapper that encapsulates how to locate and interact with a page or component, so tests express intent ('log in as X') and the selectors live in one place. When the UI changes, the model updates once instead of every test that touched that screen.
Key takeaway
Explain the underlying mental model clearly, then support it with a concrete example and its trade-offs.
