Customer Experience and Data Driven Thinking Questions

Covers the ability to understand and improve customer experience using quantitative and qualitative evidence. Interviewers look for candidates who analyze user behavior and funnel metrics, identify drop off points, use experiments or controlled tests to validate hypotheses, and balance data signals with user research and empathy. This topic includes awareness of data quality and measurement limitations, selecting appropriate success metrics, interpreting results responsibly, and using insights to prioritize and influence product or process changes that improve customer outcomes. Candidates should show structured thinking about measurement, trade offs when data is incomplete, and how to communicate data driven recommendations to technical and non technical stakeholders.
