I don't know about gog specifically, but CDPR is well known these days for not being the best place to work.
This is the video game industry in general.
In this forum, all I am seeing in a breed of platform warring for these topics, which is a shame since there is so much to discuss here
Especially as this topic does not even mention any companies by name, but is a bit more specific to software companies in general. There is a tendency to go for this kind of "flat" structure in tech right now, and it is so hit and miss specifically because oversight is either far too loose or not open enough. More importantly such structures seem more inclined to develop cliques, and those can be a wider mixed bag to function in. This is definitely something that is a joy for some and misery to others.
CDPR has same problems and benefits of any hierarchical company, but with the added game industry issues that come with it. There have been bad things said and good about working for them. Really depends on the person, but I thing self organising companies have an added issues of simply fitting it a culture in flux and more dependant on teams coalescing in a way you can function
