Your question is Prioritizing Competing Client POCs. 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 prioritize building a custom proof of concept for one client while several other high-priority projects were competing for your time. How did you decide what to prioritize, how did you communicate trade-offs, and what was the outcome?
