2. FRONTEND SYSTEM DESIGN (1 hour, Zoom and Excalidraw). The task was to architect a solution for a frontend app (no need to discuss typical system design topics like load balancers, etc). The idea is to determine a basic design and user flow / UX for the application described. The major considerations were application performance, user interactions, frontend-backend interactions (what endpoints and what kind of data and why), data structures/state, and any libraries or techniques you would use. It was important to identify performance bottlenecks and their solutions (dom rendering, lazy loading, caching, etc.).
