They mailed me by linking since they watch out my cv. The first part of the process was outsourced to an HR company (Adecco), who asked me to complete some english and excel tests. After that, an HireVue interview was set. I was confirmed during the online interview itself and they invite me at their assessment center for a group interview. Only after passing it I was invited in the Pirelli site of Milan for my 3vs1 final round.
