I applied through college or university. The process took 4 weeks.

I attended the on-campus recruitment. There are a total of 4 rounds in the process.

• The first one is a coding round where we are given 3 DSA questions based on trees and graphs, and we need to solve them in 90 minutes.
• The next round was a hackathon which is divided into 2 parts. The first part contains 1 question in which there will be sub-questions, and we need to solve it in 3 hours. The part-A hackathon is based on trees. You have to score 200/300 to qualify this round. The part-B is a video conference with a mentor where he will ask you to optimise the code you've written in the previous round, and also he will give another question to solve. The time may elapse for more than 6 hours depending on how you'll perform.
• After you qualify this round, there is a technical interview, and the questions are based on OS, DBMS, System Design, and Computer Networks.
• Then the next round is HR.

I couldn't score 200 in the part-A, hence I am not selected for the next round. I hope others will get there through this.

There was a nearest meeting cell problem based on a graph, which you can find on LeetCode discussions.
