💬 Potential Interview Questions

What are some advanced patterns in React that help in building scalable applications?
Render props, higher-order components, and custom hooks enable component reuse and separation of concerns in large-scale applications.
How do you optimize performance in a large React application?
By using techniques like memoization (React.memo, useMemo), lazy loading components, avoiding unnecessary re-renders, and efficient state management.
How do you structure a large frontend codebase to support long-term maintainability?
Using feature-based folder structure, colocated logic, reusable components, and consistent naming conventions improves scalability and maintainability.
What are the benefits of using TypeScript in a React codebase?
TypeScript provides static typing, better tooling, and early bug detection, enhancing code quality and developer productivity.
How would you handle state management in a complex application with multiple features?
Depending on the needs, combining React's built-in state (useState, useReducer, useContext) with external libraries like Zustand or Redux can provide scalable solutions.
How do you ensure consistent UI/UX across a rapidly evolving product?
By using a design system or component library, maintaining strict UI guidelines, and collaborating closely with design teams.
Describe a challenging frontend project you led and the technical decisions you made.
Example: Led a dashboard redesign, chose to migrate to React Query for data fetching to improve performance and consistency.
How do you work with product and design teams to shape new features?
By engaging in early design discussions, providing technical insights, and iterating quickly based on feedback and user needs.
What strategies do you use to mentor junior engineers effectively?
Code reviews with detailed feedback, pair programming, knowledge sharing sessions, and setting clear development goals.
