It's common to all nations, period.

It's a heck of a lot less common in Scandinavian countries, or even a large part of (Eastern-) Europe. But yeah, no facts, just an opinion i guess

For the record: not to all nations. In Russia, a really cool technical university (Bauman's, PhysTech, some faculitis of MGU) will give you some advantage in the early stages of your IT career, but not that much.

Source: am a dropout of a shitty university, still have no degree. It does not bother HRs, as far as I could see so far.

Also anecdotally I haven't noticed it in Iceland. I've been part of a number of hiring processes here and although the presence or absence of education has of course been a factor, where that education happened has been totally irrelevant.
