Next.js interviews test deep understanding of the App Router, Server Components, caching layers, and edge runtime trade-offs. Practice the questions teams ask when hiring for modern Next.js stacks.
Sample questions
These are the kinds of questions you'll drill. Real mock rounds will generate many more — tailored to the exact JD you paste in.
Walk me through the difference between Server and Client Components in the App Router.
Explain the Next.js caching layers and how you'd debug a stale page.
When would you use SSG, SSR, ISR, or PPR? Give a concrete example for each.
How do you handle authentication in a Next.js app — middleware vs server actions?
Describe a real performance issue you fixed in a Next.js app.
Reading Next.js questions isn't the same as answering them live. You need the rep — the pause, the clarifying question, the moment where you realize you forgot the framework. We put you in that exact spot, then show you what a strong answer would have looked like.
