be carefull with CSC, I have heard very strange stories about the work culture there etc.From what I know M3 to SM in accenture will probably take you 2 performance periods (depending on when you join). The best choice would be to start with ACN in the next few months, get adjusted quick and be on a top project with a good role for the start of the new performance year (1st of June officially). of course you need to perform like hell, do some business development besides, but it is manageable.advantage of ACN:there is a defined career path within ACN and even if the promotion process is not perfect...at least there is a process. each year people make the jump up, why shouldn´t you?I cannot tell you about CSC but from what I see ACN has the most transparent promotion process in the market. I would expect more politics within CSC.
