Depends on EU country of course, but any court can invalidate such clause or even entire signed employment contract without much effort, especially in such highly unilateral uncompensated unbounded case.

I am sure refusing the contract is tough decision for some but I think in a long term it is a wise move. Companies with such shaddy tactics usually are quite bad toxic places to work in and lack any reputation. Just check some other non-compete/confidentiality clause threads here in HN. You will find similar experiences.

From my experience it is extremely rare situation in EU nowadays, but I may be biased as I work with reputable companies from my network recomendations.
