Welcome to your interview.
The question is on your right: Analysis Driving Cost Savings or Efficiency. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Can you describe a project where your analysis directly led to a cost-saving or efficiency-improving outcome?
