Vantaggi
Ha ha! It's hard to say anything positive about a company that treats employees so poorly and has their PR machine writing phoney reviews on Glassdoor. Some of my colleagues were nice but they ultimately fled.
Svantaggi
A while ago AECOM had a Glassdoor rating of 2.6 and was rated one of the worst companies to work for. Enter the PR people doing damage control by writing a heap of obviously false five star reviews and the company rating is suddenly up to 3.4. Who do they think they are fooling? Instead of listening to people's complaints and taking positive action they write false reviews in a pathetic attempt to hide the truth. Who else would tell the management idiots to "Keep up the good work"? Seriously! Don't be lured into this company by their slick marketing. You'll end up feeling like a slave in a mine run by Daleks.
