I attended first round - 45 mins. Typical Behavioral Qs like tell me about a scenario when you handled a time crunching problem, etc etc.
Explained the remaining two rounds (one with technical team and another with manager which is onsite)
The interview started with introductions about the role, duties, and asking about myself - went for 10 to 15 minutes. A couple of other questions about relocating to the office sites were asked and I answered yes to all of them.
