About the role

This interview is for a junior developer building web interfaces with React. The panel is looking for sound JavaScript fundamentals, thoughtful component design and the ability to debug real browser behaviour. Clear reasoning matters more than knowing every library.

How to prepare

  1. Revise props, state, effects, event handling and list rendering in React.
  2. Practise turning a simple screen into small components with clear responsibilities.
  3. Use browser developer tools to trace a failed request, a console error and a layout problem.
  4. Review semantic HTML, keyboard navigation and accessible form labels.
  5. Prepare one project story that explains your choices, mistakes and improvements.

Common mistakes

  • Naming React features without explaining when or why you would use them.
  • Treating a visual match as complete while ignoring loading, error and empty states.
  • Reaching for a new library before understanding the underlying browser problem.
  • Forgetting keyboard access and semantic HTML.
