-There is no structure whatsoever to advancing in the company. You do the best job possible and be told you are doing so by your direct managers, but when it comes to promotions its all luck and chance. Even if you are recommended for one, no one can tell you when or if it will happen. There are rumors that a limited amount of people can be promoted each cycle so if you don't have someone at the top of the company pulling for you, it won't happen. Since employees with the same job title and exceptions have many different managers it's impossible to compare one person's work to another's.
-As mentioned, you are given a lot of responsibility immediately. Everyone is extremely busy since jobs are short staffed, so there is little to no guidance given to you. You have to figure out mostly everything on your own.
-There's a high turnover rate and the upper management doesn't seem to care too much.
