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.
