Step 1

Describe the job you want

Type the role, a short job description or tech stack, and your years of experience. Pick the interview type and how hard it should be.

  • Any role, from engineering to sales
  • Technical, behavioral, system design or mixed
  • Easy, medium or hard

Step 2

Get five questions written for you

The AI writes five interview questions for that exact role and level, each with a model answer kept aside for your feedback.

  • Matched to your stack and experience
  • Ready in seconds
  • Each question can be read aloud
  1. 1How does React decide what to re-render, and how would you avoid unnecessary renders?
  2. 2A page takes four seconds to become interactive. Where do you start?
  3. 3When would you reach for server components instead of client components?
  4. 4How would you make a long form accessible to keyboard and screen reader users?
  5. 5Tell me about a bug that only happened in production. How did you find it?
Step 3

Answer out loud, like the real thing

Press record and speak. Your words appear as you talk, so you can see what the interviewer would hear. Turn the camera on if you want to practise eye contact.

  • Live transcript while you speak
  • Camera optional, never recorded
  • Jump between questions freely

How does React decide what to re-render, and how would you avoid unnecessary renders?

Stop recording Listening

Your answer, as you speak

React re-renders a component when its state or props change, and then its children re-render too. To avoid extra renders I'd keep state close to where it's used and memoise expensive children with React.memo

Step 4

Read exactly what to improve

Every answer is rated out of 10 the moment you stop, with a few lines on what to improve and a strong answer to compare with yours.

  • A rating for every answer
  • Specific, short feedback
  • A model answer side by side

What to improve

Clear on what triggers a render and a good instinct on keeping state local. Mention that React compares the new and old trees and only updates the DOM where they differ, and say when memoising isn't worth it: it has a cost of its own.

A strong answer looks like

React re-renders a component when its state, props or context change, then reconciles the result against the previous tree and commits only the differences to the DOM. Keep state close to where it's used, split context by how often it changes, and memoise only components that are expensive and receive stable props.

Answered out loud

Clear on what triggers a render. Next time, mention how React compares trees and when memoising isn't worth it.
