Junior Frontend Developer (React)

This role is best suited for a Junior Frontend Developer who has basic experience with React, HTML, CSS, JavaScript, and Git, including personal projects, coursework, or internships. The candidate should be comfortable building UI components, implementing responsive designs, fixing bugs, and collaborating in a small remote team while continuing to develop their frontend skills. They should be proactive, able to work independently, and excited about growing in a fast-paced, product-focused startup environment.

1. What are React components, and why are they important?
   React components are reusable pieces of UI that encapsulate structure, behavior, and styling. They help keep applications organized and make code easier to maintain.

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

3. How would you create a responsive web page?
   I would use CSS Flexbox, Grid, responsive units, and media queries to ensure the interface adapts properly to different screen sizes and devices.

4. What is the purpose of Git in software development?
   Git is a version control system that helps track changes, collaborate with other developers, manage branches, and safely merge code into shared projects.

5. How do you debug a problem in a React application?
   I would reproduce the issue, inspect browser developer tools, check the console for errors, analyze component state and props, and isolate the root cause step by step.

6. What are React Hooks, and why are they useful?
   Hooks allow functional components to use state and lifecycle features. Common examples are useState for managing state and useEffect for handling side effects.

7. How would you improve the performance of a React application?
   I would avoid unnecessary re-renders, use memoization where appropriate, optimize images and assets, and lazy load components when possible.

8. Why is semantic HTML important?
   Semantic HTML improves accessibility, SEO, and code readability by using elements that clearly describe their purpose, such as <header>, <main>, and <button>.

9. How do code reviews help developers improve?
   Code reviews help identify bugs, improve code quality, share knowledge across the team, and encourage adherence to best practices and coding standards.

10. What qualities help a junior frontend developer succeed in a remote team?
    Strong communication, willingness to learn, reliability, self-motivation, and the ability to ask questions when blocked are essential for growth in a remote environment.
