1 OA (it had 5 questions, 2 coding questions from DSA, 2 from mathematics, and 1 MCQ from Python) and 3 rounds of interview. The last round of interviews was meant to be on-site in their Gurgaon office [I applied off-campus]. I applied in February and got a call from HR in May from an OA. I was able to solve all questions correctly, and thus I qualified. The interview was scheduled 7 days after the OA. The interview went well, questions weren't difficult. However, the interviewer seemed to be in a hurry in the middle of his daily work. I was sent a rejection email by the end of the day.
