Interview Experience: UST Global - Frontend Engineer

I had the L1 or Level 1 round at UST Global a couple of hours ago. And I thought I would take this opportunity to explain the process.

  • The round is 30 minutes long, and the difficulty is easy.
  • The round was focused mainly on React.
  • Before the interview, the HR asked me if I had experience with React, Redux, etc.
  • Since this is the first round, they focused on just the basics. Here are some of the questions asked -
  1. What are hooks, and how are they an improvement over class components?
  2. What are some optimisation techniques in React?
  3. What is Git, and how does it help in development?
  4. What styling library is used in React, and are there any drawbacks to using it over styled components? I'm guessing they use Styled Components at the company.
  5. What are controlled and uncontrolled components?
  6. How to write custom hooks?
  7. How to do unit testing in React?
  8. What is the difference between useEffect and useState?
  9. How to make a retry mechanism in API calling and failing in React?
  10. How to handle errors in API calls in React and show them to the user?

Will update if I hear from them again for the next rounds!
