Frontend interview practice
React Mock Interview Practice
Practise explaining React rendering, state, hooks, performance, and frontend trade-offs in a spoken technical interview.
Best for: React developers with roughly 1-5 years of experience
Example spoken questions
- 01When does a React component re-render, and how would you diagnose an unnecessary render?
- 02Explain stale closures in hooks with a practical example.
- 03How would you choose between local state, context, and an external state library?
What to practise
Focus areas for this track. Practise explaining each one out loud, not just recognising it.
- Rendering, reconciliation, keys, and component identity
- State ownership, effects, closures, and custom hooks
- Memoisation, profiling, list performance, and bundle trade-offs
- Accessible UI, testing strategy, and production debugging
How to answer more clearly
Avoid listing APIs. Explain the runtime behaviour, a trade-off, and an example from a production UI.
Mockery makes you answer aloud, then evaluates the transcript for technical coverage and missing concepts. It does not claim to predict a hiring decision.
