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).
How would you design a product metric to evaluate customer satisfaction?
Explain how you would define satisfaction, select an appropriate measurement method, validate that the metric reflects customer experience, and use it to guide product decisions. Discuss limitations, segmentation, sampling, and how you would distinguish a useful leading indicator from a lagging outcome. Your answer should be practical and suitable for a NatWest digital banking product, without assuming that one survey score fully represents customer experience.
