Pros
I'ts like a gym. It makes you resistant and strong, though you won't learn to play the sport here.
Cons
Management is toxic and lacks of the knowledge necessary. They go against their own workers if you don't play their politic game. They diminish the work of other people and the sole tool they use to push projects forward is pressure and screams. When this pressure does not exist, projects don't advance because they do not know how to drive the project. The people with talent leaves when they have the chance and they are ultimately surounded by people who plays their politic game. This ambience creates tension between different departments and even within. Highly competitive environment, but in the bad sense of the word: departments are fighting for control over the production, people tries to step on each other to claim successes and managers foment this kind of behavior, even rewarding it. Projects advance due to brute force of the workers by making extra hours. Yet, they are not rewarded. Progression is not base on merits but on posture and facade. Tools are hard to use, obsolete and internal, which means, you cannot even count them as experience for your CV. Management doesn't care about usability of their own tools and expects workers to just deal with it. It's common to have to edit files manually in order to even be able to start working with the tool. There are tools without a "new file" command or even a clone one, forcing workers to keep their own templates and duplicate files in the OS, edit them manually and replace values to just start working. Management doesn't care much about that and there are very few people and time assigned to maintain the tools because they expect people to brute force through everyting. This situation also creates conflicts between departments since each department has different priorities and they clash on each other.
