PwC Graduate - Risk interview questions

completed online application form, numerical online test, logical reasoning test and personality compatibility questionnaire. I was invited for a telephone interview which was extremely intense, the atmosphere from the get go was rigid and cold so I found it very hard to get my personality across. I hadn't prepared well enough but the questions all seem to have been similar to ones that I had found on the internet - why pwc - why risk - what do you think you will be doing day to day - name a time when you encountered difficulties in a team - have you come across a news article lately that may influence or affect the business of pwc
