Pros

Good environnement overall, some interesting assignements, you find good and genuine persons

Cons

Some offices all around the world feel like totally excluded from the Group, pay is very average, annual reviews and career progress are not standardized nor transparent, international mobility does not work anymore, accounts and expertise cannibalise themselves and the business model is not operated in the most efficient way for maximising revenues & profit and gain projects/mandates, there is no Sia culture as there used to be neither a sense of belonging
