Design and Research Methodology Questions

Covers how to clearly explain and justify both research study methodology and the product design process. For study design, candidates should be able to describe research questions, the rationale for choosing qualitative versus quantitative approaches, sampling and participant selection strategy, sample size justification, recruitment methods, design and iteration of research instruments such as interview guides and surveys, data collection and analysis procedures, steps taken to mitigate bias and error, and tradeoffs considered. For the design process, candidates should articulate discovery methods for uncovering user needs, problem definition, ideation techniques, creation of wireframes and prototypes, usability testing and A and B testing, iteration cycles, evaluation metrics, evidence based decision making, stakeholder alignment, and ethical considerations. Interviewers will assess the candidate on clarity of process, ability to justify methodological choices given constraints, awareness of limitations and tradeoffs, and how methods produced actionable insights or product outcomes.
