UBS Sales & Trading interview questions

I went to UBS Sales and Trading Superday for their internship position. The day started off with a written test. We were given a practice test beforehand but the actual test was much easier than the practice one (surprisingly). Then, we all had five 20 minute interviews in a row. Each interviewer started off with the same 'tell me about yourself' question, then some asked brainteasers, some asked math questions, and some just grilled you on why you wanted to be in S&T.
