Vantaggi
Opportunities to work on types and sizes of projects few other firms can provide - these look great on resumes. A fantastic place to work if you live for your career and nothing else.
Svantaggi
I can't speak as to the situation at other AECOM offices but the cons at Sacramento are too many to list. Worked there when it was still EDAW which was a company we were all very proud of. AECOM, in its infinite wisdom fixed what wasn't broken and the office rapidly became a revolving door of highly qualified people seeing the trend and getting out or being shown the door for not being "team players". Issues have only been compounded by current management if it can even be referred to as such. Advice to prospective employees - look elsewhere. You can't possibly be this desperate.
