PwC Consulting used to be the premier Fincance and Cost Mgt consultancy in the market, in terms of employee size and market share. Since the IBM takeover, the FCM practice has lost most of its old PwC staff, due to poor quality of new recruits, lack of investment in training and salary increases, and poor quality of work (mainly huge scale public sector PMO jobs). Many of the people who were responsible for this decline now work for E&Y BAS and FS. Expect a similar trend there.In terms of decent Finance Transformation consultancies, try PwC or Deloitte. Other non-accounting firms, that are winning lots of interesting work are Atos, Cap Gemini, and also PA Consulting. Good luck in your job search.
