Your question is Process Improvement With Data. 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 situation where you successfully improved an existing process. Explain the problem you identified, how you evaluated possible improvements, and how you gained support for the change. Include your specific contribution, measurable results, and what you learned. The interviewer is assessing ownership, analytical judgment, prioritization, and your ability to influence others when improving a process you may not directly own. Use one specific example rather than describing your general approach.
