Horrible management in every corner.
Huge politics in the company, you can easily get eaten by a power tripping lead who wants to demonstrate power and gain a promotion.
You will never get to increase your salary to your liking because apparently they decide your salary increase and you can't negotiate.
Do you work hard to grow faster and do you give your 150% to the work so you can get that promotion while creating new projects and implementing great new ideas? Well that's cool and all but nobody cares.
Can't compete with EA, Ubisoft, Google or Apple offices at all but apparently they advertise as they are the greatest in online MMO market (hint: they are not)
They can ask you to do unpaid overtime since it is in the contract you are offered, and no they don't offer contracts without it.
