Freeze up and panic!

Seriously, I think these type of interview questions are more about seeing if you can make a sound, defensible judgment call under stressful conditions than any "right or wrong" answer. Your answer will reveal much about your flight experience, training, and ability to make a decision and stick to it.

Obsess about answers to specific type interview questions like this, and you'll freak out when they ask you a question you didn't anticipate and prepare a canned answer for.

For the Trekkies: It's a Kobayashi Maru Test . .. "There is no right or wrong answer, it is a test of character."
