- Q1. What are hooks in reactjs? How many you used?

Hooks in ReactJS are functions that let you use state and other React features in functional components. I have used useState and useEffect hooks.

- Q2. Difference between Controlled Components and Uncontrolled Components
- Ans.
Controlled components are controlled by React state, while uncontrolled components manage their own state internally.

Controlled components provide more control and flexibility, while uncontrolled components are simpler to imple...

Round duration - 90 Minutes
Round difficulty - Medium
This round happened on the same day as JAM in the afternoon time. A slot of 20 minutes with respective timing was already sent to the selected students. Interview can’t be generalize as anything can happen over there and hence this was exclusively my experience.
To have a quick judgement about the person, I believe nothing is better than throwing before him/her some puzzles (mathematical/ analytical/ programming problems) and see the approach. I received back-to-back 4 problems after a quick and brief introduction. The coding problems I got were way too easy (just basics: searching & mathematical). The harder part of this round was the puzzles (tricky, mathematical, related to probability). At last, I was asked a question on DBMS and the interviewer asked if I know JAVA.

Ensure the array 'A' is sorted in non-decreasing order to apply binary search effectively.
