Not much has changed at all toward foreigners and the west in this time.
A lot has changed...But they will still prefer to hire a Polish person with less education then an skilled and professional foreigner.
Just tell you an story..,
Some time back i had plenty of free time and bored to hell plus i needed some extra cash so i taught about temporarily jobs and when i opened local job search sites like gumtree, it wass full of fast food jobs like MacDonald and KFC. I went to almost all of them and the moment i would tell them i saw the advertisement and i want to work here...they would look at me as if i told them something very unbelivebaly strange. I didn't receive even 1 call after giving resumes in so many places. that's why you would hardly find any foreigners working in even international companies like Carrefour, Starbucks, KFC etc...
Yes comparing to other western countries, Poland is still 100 years backward when it comes to mentality. But i want to be honest...alot has changed and its changing. but it will take a long time before a foreigner can call this place home...or feel home!!!
