Mars European Finance Graduate interview questions

Application with competency questions, followed by a numerical test, which is followed by a 1 hour competency based telephone interview with 2 interviewers. Interview solely based on competencies, so your typical "Why Mars" "Why this programme?" "Why FMCG". As Mars is a privately held company it could be difficult to attain much information on their processes. They do not give feedback after telephone interview though which I was quite disappointed in.
