I don't remember all the details because it has been a long time. There were just two rounds involved for me.
First rounds of interview after your CV submission is accepted is solving simple algorithm problems on a platform, submitting and waiting for a response.
The second round is having a live interview with some team members and solving some simple to basic whiteboard android problems. You generally don't have to complete everything.
Experience was good and you get response in a week or slightly more if you pass all the rounds.
