Your question is Pushing Back on Unfeasible Features. 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 were asked to build a feature that was not technically feasible, or not feasible within the timeline or constraints given. How did you communicate that, align the stakeholders, and what outcome did you drive instead?
