Hi, I'm about to start at a Big 4 grad scheme doing management consultancy. Within the programme, there is the opportunity to Strategy consulting which i want to get into. I know there is talk of smaller strategy firms like Booz (already acquired by PWC) being acquired by the Big 4. What are the key differences in strategy within the Big 4 and pure strat firms like Mckinsey etc? Exception being the clients. In addition, what are some of the exit ops?
