I am contemplating making the move to consulting via the experienced hire route. My motives for doing this are the desire for a structured career path, the chance to work alongside some very intelligent people and - most importantly for me - the fact that consulting means working with a wide variety of clients across multiple industries.However, one question intrigues me - what is it about consulting for you that stimulates you intellectually? There was a recent thread posted about the need to leave a firm being underlined when the level of effort exceeds the intellectual challenge. Extending that further, how intellectually stimulating is consulting, and why?
