Name the specific heuristics you rely on most and give examples. "Visibility of system status" catches different issues than "error prevention." Show you use them as practical diagnostic tools, not academic checklists.
Strong answers reference established heuristics (Nielsen's 10, Shneiderman's 8 golden rules) and describe a systematic evaluation process: defining scope, multiple evaluators, severity ratings, and actionable recommendations. Best candidates discuss the limitations of heuristic evaluation versus usability testing with real users.
Tests UX foundations. Candidates who know heuristics and use them practically can quickly identify usability issues. Those who cannot name specific heuristics may lack foundational UX knowledge.
