Pros

Many great developers to work with Flexible work hours

Cons

Many teams are lead and/or directed by incompetent people who focus more on advancing their own career than shipping a good product. Developers are being fired if they speak up about their leads' incompetency. HR processes fail to solve any mismanagement issues, often leading to developers quitting their jobs. The upper management is rotten to the core and full of people skilled only in sucking up to the directors. Complete mess in terms of production leading to crunch all the time. Many leads and directors lie constantly, both to their teams and their leads. People exposing those lies are often forced to leave or are straight out fired. Many developers have been asked to put up positive reviews here to hide how things really are. Low salaries, even compared to what other gamedev companies in Warsaw pay. Your career can be frozen by your lead based on lies he spreads about you and there will be no one to help you.
