Beginner Interview Questions

Definition

Common, foundational questions asked in junior frontend engineering interviews to verify a basic understanding of the Next.js framework.

Explain Like I'm New

Interviewers at this level want to know if you understand WHY Next.js exists, the difference between it and standard React, and the absolute basics of routing and components.

Real World Example

Preparing to articulate the difference between SSR and CSR clearly, rather than just reciting textbook definitions.

/* Common Beginner Interview Scenario: "How do you make an API call in the new App Router?" Bad Answer: "I use useEffect and fetch the data when the component mounts." (This proves you don't understand Server Components) Good Answer: "By default, components are Server Components. I simply make the component async, use standard 'await fetch()', and Next.js fetches the data on the server before the HTML is even sent to the browser." */

Answer

Instead of writing complex code to connect a URL (like '/about') to a webpage, Next.js acts like your computer's Desktop. If you create a folder named 'about' and put a file in it, the website instantly creates that URL for you.
