C1 - I would def. recommend considering inhouse strategy teams as a move after ACN. Challenging work, not such brutal hours, better pay. On the downside, pace is sometimes slower, you have to content with internal politics you don't usually see as an external and you don't get as much variety i.t.o diff clients/people as with ACN, but if the org is big enough there is usually lots of scope to move around and get involved in different things.
