AECOM is one of the giants in the industry. In this type of international organizations, employee satisfaction may change from location to another. My experience was with the Alberta branch so it is specific to location. The resources you will have is more than adequate however level of professionalism is questionable. Upper management is mostly coming from trades, less educated, more experienced. This could be a good thing if they could educate themselves on the level of the posts they sit in, however, it is not the case most of the time for AECOM. Favoritism is also a big problem, it does not matter how you perform if you are not from the 'neigbourhood'.
