How to approach it
The interviewer wants to see whether you understand why you need an abstraction over the UI at all: isolating tests from the markup and readability. And whether you can keep Page Object maintainable on a large project: keep asserts in the tests, extract components, and know the alternatives.
The interviewer will ask this question and listen. Think out loud and ask for a hint if you need one. When you're done, pause or tap “That's my answer”. In about a minute, your score and the points you covered show up here.
