System Design Interview for Front-end Engineers
summary
Covers how Grammarly conducts system-design interviews for front-end roles by walking through building a mini‑Twitter client. Focuses on client architecture, state management, API patterns (infinite-scroll pagination, fetch by timestamp, single-item fetch), draft persistence, error handling and accessibility tradeoffs, using whiteboard diagrams, clarifying questions, timeboxing, high-level design then module-level detail, and pragmatic recommendations rather than a single perfect solution.
