Three rounds. 1. Screener: They ask you questions based on your domain. A wide variety of difficulty levels. 2. Managerial: More domain based questions with a focus on your past experience. 3. Vibe check: They see if you mingle well with your future colleagues. It also helps to kind of get a feel about the kind of people you are working with. Cool, well thought out interview process. They keep you informed throughout and make sure you know what is going on.
