User Research and Validation Questions

Comprehensive knowledge of user research and validation techniques, including when to apply qualitative methods such as user interviews, contextual inquiry, and observation, and when to use quantitative approaches such as surveys, instrumentation based analytics, and cohort analysis. Candidates should be able to describe study design choices, participant recruitment, discussion guide creation, moderation techniques, and the execution of moderated and unmoderated usability tests and prototype evaluations. Explain how to choose methods based on research questions, constraints, and success metrics, and demonstrate how to synthesize findings into actionable artifacts such as insights, opportunity areas, personas, and journey maps. Include validation approaches such as pilot testing, split testing, and post launch measurement of key performance indicators, and show how to partner with product management and engineering to define metrics and translate research into iterative product decisions.
