Your question is Use Data to Cut Costs. 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).
Describe a time you used data to improve a process or reduce operational costs at work. Explain the problem, the data you analyzed, how you identified the improvement opportunity, and how you worked with stakeholders to implement the change. Be specific about your actions, the measurable outcome, and what you learned. We are interested in how you handled data quality, competing priorities, resistance to change, and ownership of the result.
