There were a complete 7 rounds of interviews.

1. The first was a HackerRank test with one data structure question and a 1-hour time limit.
2. Then I was called for an interview drive on that weekend at their campus. There were a complete 4 rounds: 3 technical and 1 managerial.
3. I was told on the same day that I would be contacted for further rounds but did not receive any calls for 2 months.
4. Later, after 2 months, I was called to their campus for the next round. It was a mix of both technical and managerial.
5. Then I was asked to attend a cross-continental video interview via Zoom.
6. Within one week after that, I received the offer letter.
