The first round is a quick phone call to check you are studying at uni and your grades, the second one is a group dynamic about a case which is in Spanish and English, the third one is with HR again to talk about more in depth about your experience, studies and professional goals. The fourth and fifth one are with the manager and the partner your are going to work with. I didn't get at these two last ones as I was looking for summer internships and they don't offer that here. All the interview process was face-to-face and in Spanish.
