Some people will dig in to the various tradeoffs involved with an ORM, and pick apart the structure of an ORM. And that should result in an "it depends" kind of answer.

Others are more interested in how a team is going to use an ORM; does it help junior devs write "not awful" code, how does it help me structure my application logic.

Others are stats nerds who will tell you which ones do best on benchmarks, are most popular, etc.

And many people will tell you a story about some ORMs they used, and why they liked them or not.

These answers can be useful for getting a sense of how a person thinks, but they won't tell you if the person is competent.
