React developer assessment for hiring

Evaluate React fluency with questions that test real component thinking, not memorized trivia.

What this assessment tests

  • Hooks and concurrent rendering
  • State management patterns
  • Component API design
  • Performance basics

Sample question

Which React hook lets you safely subscribe to an external store without tearing during concurrent rendering?

AI-resistant by design

Questions mix scenario judgment with code reasoning. Coding items run in a sandboxed IDE, so pasted AI output still has to pass test cases.
