There really is a lot... But the most important ones are as follows.
You get punished for going to work, you literally have to cover the desk of people that only work 2 -4 days out of the week because they are busy partying.
The systems they use are very old... Research that should take 5 minutes ends up taking at least 30.
The company is very separated... One department doesn't know what the other does and it makes it hard to work together.
