How should I prepare for both FAANG and startup React interviews?
For FAANG, go deep on hooks, performance, and architecture, plus DSA. For startups, build real projects with auth, real-time, and deployment, and practice machine coding. Aim to be strong in both fundamentals and practical building.

More FAQs in React Interview Questions at FAANG vs Startups: What's Different
FAANG leans on fundamentals, depth, and DSA: hooks internals, performance, complex state, and architecture. Startups lean on practical building: machine coding, real API integration, auth, real-time, and deployment. Both test different skills.
Deep questions on hooks rules and internals, re-renders and performance with measurement, complex state management, library trade-offs like Redux vs Context, and architecture. FAANG values fundamentals and engineering judgment, plus DSA alongside React.
Practical building: building UIs from scratch under time, real API integration, auth and real-time features, and shipping. Machine coding rounds are common, and they value day-one productivity over deep fundamentals alone.
