Pros
Hines (Globally) builds beautiful buildings, so it is a great experience for your own growth. Many of the people you may meet are smart and have worked on interesting projects. However, they are shrouded in secrecy for all the terrible treatment they have received. They tend to take it. Especially if they are women.
Cons
The company is run by White Men in the US that do not think outside the box. There is no discussion on other ways to do things, there is only their way. They continually make fun of Canada and assume we do not know how to manage buildings as they do. They also like to harbour issues instead of addressing small problems. Thus they are not leaders - they like copycat clones of themselves only. There is little to learn from them culturally (expect what not to do) but there is a lot to learn if you dive into your own experience of operating a building. They are terrible at giving support and have a self-righteous approach to all that they do. The Management in Toronto and the Management in the US do not get along so you are caught between the two constantly. Speaking up and speaking honestly will get you nowhere. Once you quit, even if you are doing the right thing with substantial notice they will undermine you and ignore you. The Canadian operations are broken and most would agree it's because of one person.
