Round 1 - Technical 

(4 Questions)

  • Q1. React vs Angular
  • Ans. 

    React is a lightweight library for building user interfaces, while Angular is a full-fledged framework with more features.

    • React is more flexible and allows for easier integration with other libraries and frameworks.

  • Q2. How is 'this' handled in arrow functions?
  • Ans. 

    In arrow functions, 'this' is lexically scoped and does not have its own value.

    • Arrow functions do not have their own 'this' value, they inherit 'this' from the enclosing lexical context.

    • Arrow functions are useful when you want to preserve the value of 'this' from the surrounding code.

    • Regular functions have their own 'this' value, which can change depending on how the function is called.

  • Q3. Rotate an array by k
  • Ans. 

    Rotate an array by k positions

    • Create a new array and copy elements from original array starting from index k to the end, then copy elements from index 0 to k-1

    • Alternatively, you can use array.splice() method to achieve the rotation

    • Make sure to handle cases where k is greater than the array length by taking modulo operation

Interview Preparation Tips

Interview preparation tips for other job seekers - Round 1 and Round 2: The interviews were chill. The panel focused on my approach rather than the results.
Round 3: The final round was taken by Aditi. She had zero conversational skills. I don't know how these people land at higher positions. I answered all of her questions confidently but seemed like she had to run somewhere. In the end, she said it was her last question for me and disconnected the call without taking any follow-up questions from me. I stared at the screen for a minute thinking no way this happened to me.
