I applied through college or university. The process took 2 days. There were 4 rounds in total, and it was an on-campus opportunity.

• OA round: 3 DSA questions which were very tough (Codeforces 2000-2100). Everyone was getting different questions. If you were getting easy questions, then it was good.
• 1st tech round (30 mins): You were given a question on paper, and you had to write the code for it on paper. Then, after 30 mins, you had to explain it to the interviewer.
• 2nd tech round (60 mins): LeetCode design problems were asked in this round.
• 3rd HR round (30-45 mins): The whole round was based on my resume in very depth.

In the HR round, they asked me about the topics that were mentioned in my resume. Do not use any fancy words in your resume to improve the ATS score.
