Interviewers commonly assess your understanding of React Hooks, component lifecycle, JSX, state management, Virtual DOM, props, Context API, and API integration. They also expect you to explain when to use different React patterns in real applications.

Redux isn't required for every role, but many companies expect candidates to understand global state management. You should know Redux fundamentals, when Context API is sufficient, and the trade-offs between different state management solutions.

Instead of asking only about features, interviewers often explore your component structure, folder organization, performance optimizations, state management choices, and how you handled API integration or complex UI interactions.

No. React interviews usually combine JavaScript fundamentals, DOM concepts, asynchronous programming, data structures, and React-specific questions. Strong JavaScript knowledge is essential for performing well in frontend interviews.

Be prepared to discuss React.memo, useMemo, useCallback, lazy loading, code splitting, efficient rendering, and reducing unnecessary component re-renders. Interviewers often ask how these techniques improve application performance.

Yes. Many companies ask candidates to build UI components, consume APIs, fix React bugs, or implement interactive features. These exercises evaluate both coding ability and your understanding of React best practices.

Common mistakes include memorizing Hooks without understanding them, ignoring JavaScript fundamentals, overusing state, failing to optimize components, and being unable to explain project architecture or design decisions.
