I applied online. The process took 2 weeks. I interviewed at UBS (Weehawken, NJ) in Mar 2016
Interview
First part of the interview was a phone call, after that I was invited to a Superday in Weehawken. Mostly behavioral questions, I spoke to several interviewers one on one.
The best way to prepare is to know UBS history and culture, be knowledgeable about various types of products, and a basic understanding of what is going on in the market. I prepared by reading UBS' house view publications.
