This question evaluates a candidate's product-thinking and usability analysis skills, specifically application of heuristics and accessibility standards alongside abilities in redesign proposal, success-metrics definition, and experiment/telemetry planning.
Pick a digital product you use daily. Identify one specific interface you love and one function you dislike. Using usability heuristics (e.g., Nielsen) and accessibility standards (e.g., WCAG), analyze why each succeeds or fails. Propose a redesign for the disliked function, define success metrics and guardrails, and outline an experiment or telemetry plan to validate the change while avoiding novelty effects.
