I started with the Model layer and listed out the obvious stuff: tracks, playlists, playback state.
Start by clarifying requirements and scope, then walk through the MVC components for a music player, explaining how they interact. Focus on separation of concerns, data flow, and trade-offs in design decisions, while keeping the discussion interactive and tailored to Meta's scale.
Pro tip: Emphasize how MVC enables testability and parallel development, and proactively discuss how you'd handle real-time updates and offline mode—common in music apps—to show depth beyond basic architecture.
Ask questions to understand core features (playback, playlists, search, offline), scale, and platform (mobile/web). This ensures your design addresses the right problems.
Outline data entities like Song, Album, Artist, Playlist, and User, and how they relate. Discuss data storage, caching, and synchronization with backend services.
Describe UI components (player controls, playlist view, search) and how they observe model changes. Highlight reactivity and platform-specific considerations.
Explain how controllers handle user input, update the model, and select views. Discuss routing, state management, and coordination between components.
Address scalability, performance, offline support, and testing. Compare MVC with other patterns (e.g., MVVM) and justify your choices.
