Pay leaves a lot to be desired.
There is very little training and development in place within certain orgs, so you need to be self-sufficient.
There are a million levels of middle management, so everyone is a VP of something, and nobody is good at their job.
People in all levels of management within certain orgs are completely incompetent. The Peter Principle is how it is best described.
Everyone there thinks that because they work there, their (blank) doesn't stink. The arrogance is obnoxious.
If you ever need help with anything, don't expect to get helpful answers from anyone. Plan on searching internal systems and learning on your own.
Forget product training. Better use Google and YouTube.
Managers are not your friends, nor are the other employees. If you say something to someone, trust that everyone will know, so keep it related to work.
The people there are only in it for themselves and will happily stab anyone in the back to get what they want.
If you aren't in the inner sanctum, you will feel like an outsider. Very clicky environment.
