UBS Senior Position In Risk Modeling interview questions

1) email from HR 2) short phone call from HR to make an appointment 3) 20 min. phone call about my cv 4) half an hour phone interview with two managers (direct and statistician): quite a long introduction about the firm and the team, questions about motivation to switch a job, dates for being available to the job, behavioral questions in a certain situation, statistical questions about risk aggregation. 5) rejection (next step was to be a R/CRAN programming exercise).
