There were 4 rounds:

• The first round was a programming test with two programs (one simple, one hard) and 5 multiple-choice questions on command-line scripting (not very sure). This test was conducted on HackerRank.

• The second round was a technical round. As I was a fresher, the interviewer asked easy and popular questions from academic subjects where I was comfortable.

• The third round was a managerial round where hypothetical questions, puzzles, and normal conversation were used. The interviewer was pressuring me to check my confidence.

• The fourth round was the last round. The interviewer asked me some technical and non-technical questions and requested I write some small programs. The technical questions were only from networking.
