took a numerical test consisting of 40 questions, had to finish in 35min. And then invited to a face-to-face interview with a line manager from Operations. Asked basic questions like: Why IB, Why UBS, Why Operations. and I prepared well for those questions. And then they asked some basic competency questions. I would say have a look at the UBS website, under the interview preparation section, they have actually listed the 7 Core Competencies that they are looking for. just prepare yourself according to that list. they won't ask a lot of unexpected questions. the interview was only 30 minutes.
