At first HR called me and invited me to a phone call with the team leader. On the phone asked me questions about the degree and availability for work. In the interview they asked me theoretical questions about models and how I would implement them. They didn't come back to tell me that I wasn't accepted.

It was quite straightforward. There were 2 rounds. The first round was about basic understanding of machine learning. The second interview was in-depth asking about the key concepts that I have learned along the way.
