UBS Quantitative Analyst interview questions

I was really surprised by the attitude of UBS towards the process as well as the candidate's and their own time. After a quick chat with HR, they wanted to sign me up for SIX interviews, over 45 mins each, which sums up to almost 5 hours of meetings for just one recruitment stage. Fortunately, they've agreed to squeeze it to 2.5 hours for the whole process, but having to introduce yourself and go over your CV 4 or 5 times is not necessarily a good use of one's time. The meetings with the team members were very nice and interesting but it was probably the most stretched up recruitment stage I have participated in.

Questions mainly revolved around Derivatives and Risk management, Securities and Portfolio Managements, Credit Risk, Exposures, time series and basic statistics around hypotheses testing, p values , t test , F test , BLUE, regression analysis and python.
