Phone call. We went over my CV, why i would like to work for UBS, and this role in particular. So basically, we went over my whole CV, and particularly job related experience i accumulated. Then, we discussed my Bachelor studies, which were known by my interviewer, since a friend worked there before me and connected me. Job related extra-curricular activities were only important once being job or topic-related. A pleasant interview, nothing very complicated, they just wanted to know more about me.
