Tell me about a time you led the front-end implementation of a React feature that required coordinating with designers, backend engineers, and product stakeholders. How did you manage trade-offs, timelines, and stakeholder expectations?

Sample Answer

At my last job I led the front-end build of a new analytics dashboard for ~50k monthly users. I owned the React implementation and coordinated a team of 2 designers, 3 backend engineers, and a product manager. We had a hard deadline for a trade show in eight weeks, so I prioritized an MVP with core charts and lazy-loaded widgets. I negotiated scoped UX changes with design to reduce custom animations by 60% and worked with backend to deliver paginated endpoints instead of full dataset exports, which cut API payloads 75%. I drove twice-weekly syncs, shared a living release checklist, and demoed incremental builds; the result was shipping on time, reducing initial load from 6s to 1.8s and getting positive feedback from 85% of pilot users.
