I am unsure if this is just filled with trolls or actual people
There are both here.
whether it be what office life is like, the general disposition and temperament of people, culture,
Office life is often a bit more formal than you may be used to. It depends a lot which sort of office your in, and where it is in Poland. Work ethic etc. can vary according to which part of Poland you're in.
About the people, again it can vary from place to place. In general, they can seem formal to the point of hostility with people they don't know, and very warm and friendly with people they know. You might notice that in offices too. People do tend to value their privacy, especially if they don't know the people they're talking to.
About culture, that's a really big (and vague) question. Do you mean the arts, or something more anthropological? If it's the latter (and this should chime with what I've just written) people can be quite reserved and correct outside the home, and let their hair down in private.
Not all Poles are the same though. The difference between what people in Australia call 'bogans' (millions of these in PL) and more 'refined' people is huge. Don't be taken in by outside appearances though; here first impressions can deceive.
