  1. I suggested possible approaches, but he guided me towards the right direction after which I was able to come up with the binary search approach. Solved and wrote the code, and discussed the time complexity.
  2. Given a number N, find the number of integers from 1 to N that have the odd number of factors. Only approach and time complexity were discussed, he seemed satisfied.

Round 2(Projects+Problem Solving): Discussion on projects, open-source contribution, and internships. She asked me what was my individual contribution in each of the projects, and why I used a specific database(MongoDB). After that, 2 questions were discussed.

  1. Gave an approach using the map, and discussed corner cases. After reviewing the code I was able to identify mistakes as well. She seemed satisfied.

Round 3(Techno-Managerial Round): This round was with a Senior manager. 

  • After a brief introduction, he discussed my projects and internships.
  • Then, he asked why I was interested in joining PayPal, the team I’d like to work with, strengths and weaknesses etc. Wasn’t a very pleasant round, he seemed a strict person.
  • I had a research internship stated, so wanted to know why I want to work in corporate world.


  • The only thing is to practice as many questions as you can from GfG, Leetcode, etc.
  • Though I had also done PayPal tagged questions from GfG, I wasn’t asked any of them.
  • Staying calm and confident during the interview helps a lot.
