The way as they inform me for the interview was by mail, I sent them my CV a couple of months before through his web site. My interview was split in two ways. First in the same room with the other candidates for the position, we did a Test about our personality, the questions were about our work team, if we tolerate other cultures, etc. The second part was a personal interview with a responsable of the department of HR, and this interview the questions was as in any other interview, studies, previous experience, etc.
