now independent but having worked in both Deloitte Consulting and CC (and hired several people from Deloitte into Capgemini Consulting), I'd say BIS has a very different feel. Deloitte is big, hierarchical and structured - people have lots of toolkit suport but find it difficult to escape their silos. CC BIS is small and gives good stretch opportunities across all their service lines - IT strat thru op model / org design etc. Hours and overall ethic are comparable. Deloitte offices are a million times better than the Wardour St slum. CC culture more open and team-oriented; lots of 'boomerangs' who leave and return, which is a good sign. Make it to partner at Deloitte and you'll be a whole lot richer though. so where did you choose?
