Interview guide
React interviews probe rendering behavior and hooks discipline — why re-renders happen, effect dependencies, state architecture — with senior rounds extending into performance profiling and design-system trade-offs.
Rendering model: reconciliation, keys, what triggers re-renders
Hooks: useEffect dependencies, useMemo/useCallback judgment, custom hooks
State management: lifting state, context limits, Redux/Zustand trade-offs
Performance: memoization, code splitting, virtualized lists
Forms and data fetching patterns: controlled inputs, suspense, caching
Practical build: a component with fetch, loading, and error states live
Practice explaining exactly when a component re-renders and how you'd verify it with the Profiler — interviewers use re-render reasoning as the fastest proxy for real React depth beyond tutorial experience.

Directly — interviewers build questions from your resume's claims, so every skill and achievement listed becomes fair game. A tailored, honest resume steers the interview toward your strongest material; an inflated one hands the interviewer traps you set for yourself.
