I recently gave an interview for the position of react developer . Here are the few questions which I remember from the interview that can help you and me also: (I have a total of 5 years of exp.) 1. Started with some basics of Javascript like deep copy/shallow copy, ES6 features,  2. React questions which were on hooks, refs, class component lifecycle and doing it in function based ones, passing props from parent to child and vice versa, contexts. 3. Redux questions (they were very much focussed on redux and asked me to implement redux structure from scratch in a sandbox, which I couldnt) 4. Unit testing libraries. 5. what are the UI libraries I have used like material UI, bootstrap etc. 6. more followup questions on what challenges I faced in the last project. What approach I will be using to start a new react project like the folder structure and third party libraries.

Diff btwn functional and class based component, how can we replicate lifecycle method in functional , component, js questions like closure, hoisting, let var, const , coding question to remove duplicates from given , also asked me to create a react form with validation , intrview duration 45 mins .
