The last trip was for 4 months near Lublin - the most important thing was that there were no problems with the PO, I had quite experience here, because I was traveling essentially as a ready-made specialist, since our work in the city "got up". I liked the efficiency of the company's employees, both at the start (docks, visas, etc., etc.) and in Poland already. The card is Belarusian, and money came to it since I was officially employed in Belarus. And by the way, you can pay with a card in Poland as well. We lived in a room with three people (there is no point in describing it - everything was OK, clean, appliances, etc.).
Either I was lucky that everything went smoothly, or just a normal company. it makes little sense to talk about the local flavor of Poland and the jokes and difficulties, here everyone has their own. From the point of view of work + payment, everything is on time and without cheating
