Frontend Developer

This role is best suited for a Middle Frontend Developer with 4–7 years of experience building user-facing applications using React, Next.js, or similar frameworks. It fits someone who enjoys crafting clean, responsive, and intuitive UIs and is comfortable integrating REST APIs and managing asynchronous data flows. The ideal candidate is familiar with chat-based interfaces, user feedback patterns, and focused on simplicity and usability.

1. How would you structure a React or Next.js frontend to keep the UI simple and maintainable?
   I focus on small, reusable components, clear separation between UI and data logic, and consistent folder structures. This keeps the codebase easy to reason about as features grow.

2. What key considerations do you take into account when building a chat-based user interface?
   I prioritize message ordering, real-time feedback (loading, typing indicators), accessibility, and clear visual distinction between user and system messages to ensure a smooth conversation flow.

3. How do you handle asynchronous API calls in React applications?
   I use async/await with proper loading and error states, often abstracting API logic into service layers or hooks to keep components clean and predictable.

4. How would you design a responsive UI that works well across devices?
   I rely on flexible layouts using CSS Grid or Flexbox, mobile-first design principles, and thorough testing across breakpoints to ensure consistent behavior.

5. What patterns do you use to manage UI state in a frontend application?
   For local UI state, I use React hooks like useState and useReducer. For server state, I prefer tools like React Query to manage caching and synchronization.

6. How do you integrate document retrieval and evidence presentation into a frontend UI?
   I design clear information hierarchies, use progressive disclosure for large documents, and provide visual cues like highlights or previews to guide user attention.

7. How do you ensure good user feedback during long-running operations?
   I always show loaders, skeleton screens, or progress indicators, and provide meaningful error messages so users understand what’s happening.

8. What steps do you take to optimize frontend performance?
   I use code splitting, memoization, avoid unnecessary re-renders, and optimize asset loading to keep interactions fast and responsive.

9. How do you ensure frontend code quality in a team environment?
   I rely on code reviews, linting, consistent formatting, and shared component standards to maintain quality and readability across the team.

10. How do you approach learning new UI patterns or frontend technologies?
    I experiment with small prototypes, read documentation and real-world examples, and gradually introduce new patterns only when they clearly improve the user experience.
