Kontras
Not a place to build your career unless political games are your thing. This place is famous for its backstabbing. Managers won't help you succeed. There is no training or career development opportunity. Teams are basically non-existent; everyone is out for themselves. Everything is about appearances. The reality is that innovation and independent thinking is not appreciated and often actively discouraged, the "really smart people" have been around so long that they lack fresh ideas, basically dead wood who have learned to play the game and ride out the remainder of their careers. If you are passionate about your career and want to take the next step, this is not the place for you. It is a black hole, and your professional resume will be the first thing to get sucked into it.
