Technical Interview Round-1

1. https://www.geeksforgeeks.org/given-an-array-of-numbers-arrange-the-numbers-to-form-the-biggest-number/
2. https://www.geeksforgeeks.org/rearrange-characters-string-no-two-adjacent/

I was able to code both the problems after some hints from the interviewer. Don’t hesitate in asking for hints if you got stuck.

Technical Interview Round-2

1. https://www.geeksforgeeks.org/given-a-binary-tree-how-do-you-remove-all-the-half-nodes/
2. Given 2 types of operations:
   1. C1 C2 Connect: connect 2 cities
   2. C1 C2 isConnected: check if 2 cities are connected or not and return True or False accordingly
   3. Sample Input
      • 1 2 Connect
      • 3 4 Connect
      • 1 2 isConnected
      • 3 5 isConnected

I was able to code 1st question and in 2nd question, we had a good discussion on approach(ran out of time for code).

Tips: Make a strong grip on Data Structures and Algorithms. Give your interview just like a discussion with interviewer. Time Management is necessary.

Verdict: NOT SELECTED
