Your question is Staying Motivated Through Ambiguous Work. 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).
What motivates you in your work, and tell me about a time you had to create your own direction to stay engaged when the problem, priorities, or success metrics were still unclear. How did you keep yourself focused, and what was the outcome?
