Good luck finding companies that after covid don't require at least a couple of days per month on site, other than startups eager for personal.

There are plenty of them out there, but they will expect to hire you are a freelancer/contractor, not an employee. Hiring an 'employee' across borders, even in the EU, is a lot of work, unless you use a third-party.

The advantage is you (worker and company) usually pay less taxes, but there are a few disadvantages that put most people off - need to deal with taxes, may need to pay your own social insurance, banks may make it harder to get mortgages. The 'protections' of employment at the end of day means nothing in most EU countries.

(Been working like this for well over a decade - never going back to a job with required office hours again)

Even I, who doesn't require anyone to be in any sort of office (we don't even have one) only hire people from the same country my company is registered in. I've hired full time employees from other countries before, but it's quite the hassle bureaucracy wise.

So yeah, I'm sure it's possible to find remote work from Croatia, especially in Europe cause it's a bit less hassle to employ someone across borders between EU countries. But I do think the chances of finding even a remote job are higher if you're based in a country with plentiful employers.
