I've built React apps before, plenty of them, but muscle memory is a real thing and mine had completely atrophied.
Start by clarifying requirements and constraints, then outline a component architecture and data flow before coding. Implement incrementally, explaining your decisions and trade-offs as you go, and test edge cases.
Pro tip: Verbalize your thought process and trade-offs; interviewers value clear reasoning over silent perfection. If stuck, simplify and state your assumptions.
Ask questions to understand the app's purpose, required features, and constraints (e.g., time, libraries, API endpoints). Confirm expected behavior and edge cases.
Sketch component hierarchy, state management, and data flow. Decide where to fetch data and how to handle loading/error states.
Build a minimal working version first, then add features. Write clean, modular code and explain your choices as you code.
Test with empty data, errors, and slow networks. Ensure accessibility and responsiveness if relevant.
If time permits, refactor for readability, extract reusable components, and discuss potential optimizations.
