Build interactive user interfaces with React hooks, state management, and API integration.
About This Assessment
React developers are among the most sought-after roles with over 100,000 specialists in the US and 42,000+ web developer openings. This assessment verifies practical React coding skills in a market flooded with bootcamp graduates and candidates padding resumes with framework names. Hands-on validation of component design, state management, and API integration separates real competency from tutorial completion.
What Candidates Will Do
Build a multi-component React application (e.g., dashboard, product listing, task tracker) using functional components and hooks
Implement state management with useState and useEffect, handle form inputs and validation
Fetch data from a REST API (provided mock API or JSON server), display loading/error states, render data in a list or table
Add routing with React Router for multi-page navigation, implement basic styling with CSS modules or styled-components
Automated Grading
Verify React app builds successfully, components render expected DOM elements, API data fetches and displays correctly, form submissions update state, routing navigates between views, event handlers trigger expected state changes, code uses modern React patterns (hooks not classes), no console errors, responsive to basic user interactions
Environment
Ubuntu 22.04 VM with Node.js 20+, npm/npx, create-react-app or Vite pre-configured, JSON Server or mock API running on localhost, Git, and a headless browser for automated UI testing (Puppeteer/Playwright)
