Pros
AECOM is a really great company that re-morphs every 2-4 years due to it's growth and evolving shape to drive and manage this. I joined 3+ yrs ago and have loved it ever since. YES it is hard work and sometimes I wish the pace was slower but honestly that would bore me. If you are prepared to work hard and evolve yourself as the company grows then you will love working for AECOM. I have a great boss and work with really skilled and dedicated professional people around me too. The constantly evolving shape always presents new exciting challenges locally and globally as we deliver mega projects for our clients.
Cons
In our business line we work hard and play hard, sometimes this is tiring and we need to fight to keep a work life balance which is important for us all. Sometimes the IT and system lag behind the growth curve but that's normal I think in a company that grows faster than it's competitors, just another hurdle to adapt to. Salaries could always be higher, true, but it's more important that you enjoy the role you do and the team you work in long term.
