do you have any "success story" of foreigner people who could find the job without being transferred?
I lived 12 years in Poland, and the only such cases I saw were in information technology, and those guys has some serious qualifications and experience. They now own their own web design company in Poland, and it's doing very well.
Things are much harder in business-related fields, though, unless you really have something to sell in your CV and know the local language. Poland turns out a massive surplus of graduates with degrees in business, administration, marketing, economics and related fields each year, and only a fraction of those find relevant jobs, even those with masters degrees and MBAs. I wouldn't count on finding a job after arriving in Poland unless you had 1) serious qualifications and experience that make you stand out on the very competitive job market; 2) a pretty decent working knowledge of the local language, including speaking and writing at a reasonable level of fluency; and 3) lots of very useful contacts and connections close to those who make real hiring decisions. I'm sure exceptions exist, but it's not very wise to make plans based on exceptions and luck.
Otherwise, I would say that you are wasting your time trying to find work in Poland when there are much better opportunities elsewhere for someone with your qualifications. That is, unless you go the classical route of finding work in the West and getting transferred to Poland at Western wages.
Why are you interested in Poland, in particular?
