This can be an intimidating question to answer on the spot, but that’s why I’m telling you about it now! Editors typically ask this in a very genuine way—an interview is an easy way for them to get feedback directly from a reader. Brushing up on a few back issues should spark a few ideas (and is good prep overall), but the key here is to use soft, constructive language. Instead of “I hate this,” it’s, “I’d love to see more of this.”
