They wrote me an email telling me I was selected for an interview and after one week I had a phone call. The recruiter asked me to talk about myself and about what I was doing at the moment. Then he talked about what his department was doing and how the intern was structured. He also asked a little bit about some projects I did and how I see myself in 10 years. At the end he asked me if I had any questions: ask as many as you can, also logistics!
