Vantaggi
The company is pretty good at identifying talent and moving them up the "corporate ladder", however the fashion in which they do it can be somewhat unsettling sometimes. While it may be just following protocol, you really have no idea what is going on when an opportunity opens. That said, depending on your department, the salary can be excellent or the salary can be under par. In general I think they are competitive especially for their market, but nowhere near over the top. The offices are professional and very well maintained and is overall a great place to work from the people you work with to the building they are headquartered.
Svantaggi
One of the biggest downsides that was faced while I worked at AMC was the lack of communication. Departments made decisions that affected other departments on a regular basis without informing or involving them in the discussion. But when the decision was made, that was it. Also a personal distaste is bringing something valuable to the table does not mean it will be taken advantage of. While it may be managers dealing with those above them, whatever the cause, it is a loss to AMC as a company due to politics.
