KPMG Student Vacationer interview questions

There are different questions at different stages. The video one has: why do you want to work with us? Why KPMG, business stream? Describe a situation where you used innovation? Name a situation where a social relationship turned into a professional one through networking. The one with the managers is quite long (1hr) but very relaxed. Mostly behavioral questions (i.e. use STAR method). Also a couple of questions regarding the industry and one was a bit of a case study (not a proper study, just what would you do if this was happening in the company)?
