Next.js Developer Assessment Template

Battle-tested next.js developer template tuned for real hiring loops: app router & server components, server actions & data fetching, streaming, suspense, partial prerendering, rubric weights you can edit, and integrity AI on by default. App Router experience commands a clear premium right now, and most candidates are mid-migration; testing both Pages Router habits and Server Component intuition separates the field cleanly.

Sample questions from this template

A preview of the questions you'll see when you use this template.

Which of these is the most idiomatic way to handle app router & server components in production?

  • A.Hand-rolled implementation with no library support
  • B.Battle-tested library + thin abstraction
  • C.Copy from the latest blog post
  • D.Avoid the pattern entirely

  • A.Application logs at INFO level only
  • B.Recent deploy diff + relevant trace
  • C.Number of open tickets

Hint: Prefer clarity over cleverness; tests count.

CodingHardQuestion 4

Refactor the supplied snippet to fix a subtle bug in route handlers & middleware without changing the public API. Explain the fix in 2–3 sentences.

Hint: Read the tests; they encode the contract.

EssayMediumQuestion 5

In 200–300 words, describe how you'd evaluate a tradeoff between app router & server components and caching primitives (fetch, revalidate) on a real project.

VideoEasyQuestion 6
