As far as I know - and a quick google search confirms this - it is typical for a European resume/CV/job application to include the applicant's age, marital status, number of children, and even a photo (race/ethnicity).
(Not certain if your post implied that European companies are more privacy-minded, just wanted to point out that that's debatable).
There are no typical European CVs. Every country will have its own style.You won't see any pictures in the UK for example, but it's still not uncommon to see one in PL.
Photos are commonly attached to resumes in the following countries: Germany, Austria, Greece, Netherlands, Sweden, Switzerland, France, Belgium, Spain. Date of birth or age: Italy, Germany, Austria, France Finland, Norway, Sweden, Portugal, Czech Rep, Hungary, Romania, Greece. Similar for Eastern European countries, or for marital status and/or number of children, place of birth, etc. Does that cover enough Europe/personal information irrelevant to the candidate's ability to perform their job for you?
If anything, the UK CVs stand out among European CVs as being much more like the US resumes, i.e. less invasive. Back to the context of this thread, for the parent to point to Europe as a protector of privacy for the job seeker is disingenuous.
