Usability Testing and User Research Questions

Focuses on planning, designing, conducting, and analyzing usability studies and broader user research to surface user needs, pain points, and behavior. Candidates should know how to define research goals and questions, design tasks, recruit representative participants, choose between formative and summative approaches and moderated and unmoderated sessions, and select appropriate test formats such as in home, lab, or remote testing. Includes facilitation techniques, observation and note taking, qualitative and quantitative analysis, synthesis of findings into actionable design recommendations, and how to cite user quotes or data to support product decisions.

For an early prototype of a new checkout flow, describe how you decide whether to test a low-fidelity clickable prototype or a high-fidelity interactive prototype. Consider research goals, what you need to learn about interactions and visuals, resource constraints, and validity of the findings.

You observe mixed signals: analytics show a 25% conversion lift for variant B in an A/B test, but qualitative usability sessions consistently report user confusion and negative quotes about the same variant. Describe how you would synthesize these contradictory results, what additional analyses or follow-up research you'd run, and how you'd recommend product proceed.

Design an operational plan that coordinates A/B testing (experiments) with qualitative usability testing to validate UI changes before full rollout. Include timelines, responsibilities (product, engineering, research), gating criteria for rollout, instrumentation and metric definitions, and steps to avoid confounding effects across studies.

Compare heuristic evaluations and usability testing by describing when each method is more effective, the expertise required for a robust heuristic review, typical deliverables, and how you would sequence or combine both methods during product discovery and validation.

During a moderated usability session, what note-taking and observation techniques do you use to capture both quantitative and qualitative data? Describe tooling, shorthand conventions, timestamping, and how you capture non-verbal cues and verbatim quotes to make later synthesis easier.
