Your question is Hardest Project and Why. 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 the most challenging project you worked on and why it was challenging. Focus on a specific project, the constraints or competing priorities you faced, and the actions you personally took. Explain how you made decisions, worked with stakeholders, and measured the outcome.
