What is Next.js?

Next.js is a React framework that enables full-stack development with server-side rendering (SSR), static site generation (SSG), and API routes. Built by Vercel, it simplifies building modern, production-ready web applications.

Next.js interviews assess your understanding of rendering strategies, data fetching, API routes, middleware, and deployment. You'll discuss performance optimization, authentication, and how to build scalable applications.

Next.js expertise is increasingly valuable for full-stack roles. Master the framework and you'll be ready for roles at companies building production web applications.

Reading answers is not the same as giving them. Sit a full mock interview and get scored on how you actually explain them.
