Had a telephone interview with member of HR, very relaxed and overall lasted about 20 mins. All competency based questions and a few about why UBS and why operations. Heard back about two months later and was invited to an Assessment Centre. I was to have 3 interviews and a numeracy test. Numeracy was fairly basic but everyone felt like they'd struggled in the time allowed but we all passed. Then the interviews with different teams within operations. All informal and relaxed. They started off with a brief outline of the what the team did and what we should expect to do daily. Did not get a role in operations but was invited to another assessment centre with a different division.
