UBS Operations Analyst interview questions

I was prescreened through a phone call with the head of HR. They then set me up for an interview in Jersey City a few days later. I interviewed with a total of 5 people each one on one. The first interview was by far the most difficult. The HR manager came in wearing pink pajamas and sneakers. The questions she asked were not difficult, but her ice cold demeanor made it difficult or impossible to create rapport. I would compare the first interview with an interrogation. The next four 1:1 interviews were much more pleasant and generally assessed whether we could comfortably work together.

I sent my resume and transcript and there is an interview with two department managers. They ask me about UBS, what do they do and what departments they have. They ask about my working experience. The whole process took 15 mins.
