I'd say it's good to practice some questions about libraries that are usually used, for example React Router, Redux, redux-saga. Also prepare yourself to answer the more popular questions like: What is the difference between the Virtual DOM and the DOM; What common patterns are used and why (HOC is one of them).
Maybe they'll also ask about the lifecycle methods of a component, so they might ask "Can I make an HTTP request inside a component's constructor"?

Some questions to keep in mind:

  1. How does React rendering work?
  2. How do we cancel a fetch HTTP request, in order to prevent setting state on an unmounted component?
  3. What does the render() method from React.Component return? (this shows that you know the difference between a React component and a React element)
  4. What is babel and webpack used for in a React application?

I'd advise that you look up React Hooks if you haven't yet. That might be a topic they want you to know.

Here are some resources you might find useful:

 

Thank you for taking the time to reply to my comment! I will definitely check these resources out and make sure I know the questions mentioned for my next interview. Thank you!
