Design Impact and Metrics Questions

Assess the ability to connect concrete design decisions to measurable product and operational outcomes. Candidates should demonstrate how they select appropriate key performance indicators, define success criteria, specify instrumentation and event tracking, design and run controlled experiments such as A and B testing, and interpret quantitative results alongside qualitative research. Examples include merchant adoption rates, order completion rates, customer satisfaction scores, and operational efficiency gains. The evaluation should cover avoiding vanity metrics, controlling for confounders, using leading and lagging indicators, and translating measurement into prioritization, trade off decisions, dashboards, and continuous monitoring. Deliverables to cite include metric specifications, experiment plans, dashboards, and before and after comparisons that clearly attribute impact to design work.
