Frontend Developer (React)

This role is best suited for a Junior Frontend Developer with basic experience in React, HTML, CSS, JavaScript, and Git, including personal projects or coursework. The candidate should be comfortable building responsive UI components, fixing frontend issues, and collaborating in a small remote product team while continuing to grow their frontend engineering skills. They should be proactive, able to work independently, and interested in fast-paced startup environments focused on AI-powered web products.

1. What are React components, and why are they useful?
   React components are reusable building blocks for user interfaces. They help organize code, improve maintainability, and make it easier to build consistent UI elements.

2. What is the difference between props and state in React?
   Props are data passed from a parent component, while state is internal data managed by the component itself and can change over time.

3. How would you make a web interface responsive?
   I would use flexible layouts, CSS media queries, responsive units, and modern layout systems like Flexbox or Grid to ensure the UI works well on different screen sizes.

4. What is the purpose of Git in frontend development?
   Git helps developers track changes, collaborate with teammates, manage feature branches, and safely review and merge code.

5. How do you approach debugging a frontend issue?
   I would reproduce the issue, inspect the browser console and network requests, isolate the problem area, and test fixes incrementally.

6. What are React hooks, and why are they commonly used?
   Hooks allow functional components to manage state and lifecycle behavior. Common hooks like useState and useEffect simplify component logic and improve code readability.

7. How would you optimize frontend performance in a React application?
   I would minimize unnecessary renders, lazy load heavy components, optimize images and assets, and use memoization when appropriate.

8. What is the importance of semantic HTML and accessibility?
   Semantic HTML improves readability, SEO, and accessibility for users relying on assistive technologies such as screen readers.

9. How do you handle collaboration and code reviews in a remote team?
   I communicate clearly, write understandable code and commit messages, respond constructively to feedback, and proactively ask questions when needed.

10. What qualities help junior frontend developers grow quickly?
    Curiosity, consistency, willingness to learn from feedback, strong debugging habits, and building real projects are important for rapid growth.
