Can you share your opinion about other countries as well? It's an interesting statistic which I, suspect, not many would be willing to discuss publicly and non-anonymously.
Let me reinstate that also this is not universal. We had very good candidates which didn't inflate the resume, thus my point that I really cannot look at the CV by itself. This is very detrimental for both.
I took "germans" as a stereotypical example here. Thinking back, most qualified applicants anywhere in EU are in a similar ballpark. I would say a small amount of inflation is common, but senior applicants generally match much more closely the qualifications they presented. I didn't have many applications from other eastern countries to say anything else.
I'm also not an HR guy. I just participate in the hiring process when the need arises.
