It was three rounds. Before the three rounds a recruiter contacted me and arranged the meetings. She was always the POC. First interview was with a person in India, then China and then with HR department.

It was three back to back interviews. As it's in the middle of the pandemic, the interviews were conducted through video calls. There was a bit of miss-communication and technical difficulties at first regarding the interview process and schedule with the HR (they said they will contact me after the first interview session of whether or not I'm eligible for the next round of interviews but they didn't contact me after the first one and I was quite surprised when they told me that the next interviewer was already waiting for me), but in the end, it went just fine. They could explain the role quite well and wanted to make sure that I have the right expectation of the role.
