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 -
- What are hooks, and how are they an improvement over class components?
- What are some optimisation techniques in React?
- What is Git, and how does it help in development?
- 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.
- What are controlled and uncontrolled components?
- How to write custom hooks?
- How to do unit testing in React?
- What is the difference between useEffect and useState?
- How to make a retry mechanism in API calling and failing in React?
- 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!
