Swiss Re Market Risk Credit and Equities interview questions

I first had a telephone interview and then 4 interviews over 3 hours; 2 in person in London and 2 by VC from London to New York and Zurich. I enjoyed meeting 3 of the interviewers, however I thought the Swiss person who attended in London was incredibly aggressive and rude and this completely put me off the company. He would ask a question and not given any opportunity to respond, just cutting me off at the first opportunity. After about 15 minutes he seemed to become concerned about catching his flight back to Zurich.
