Your question is Leading Through Product Ambiguity. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you had to make progress when the product direction or market landscape was changing quickly and you didn't have complete information. How did you decide what to prioritize, how did you keep stakeholders aligned, and what happened?
