Why companies in Poland don't answer back sent work applications?

I have sent several work applications to different countries among those Poland. What I have realized is that companies in Poland almost NEVER answer back.

I mean, in other countries companies almost always answer you and let you know that your application has been received and if your application has been successful or not.

I was interested in a position in Poland at a company from my home country, the HR department in Poland never replied my emails, I had to personally contact the HR department at my home country, tell them I was interested at a position in Poland, they gave me further advice and I finally got the position.

But what is wrong with companies in Poland which never answer back? why do they do this? There are probably to few jobs and they want to jealously keep them for close friends/relatives ?

In Poland there was always (since Russians have left) employer market, so companies didn't have to care for good appearance in order to still get hundreds of applications. Thus answer to inquiry is in their eyes something excessive.
