You can easily get jobs in Germany without passing tests. Your options may merely be limited, but that's part of why I suggested this would be easier for a younger person. I got a job at UPS in Germany doing data entry and I didn't understand a stitch of German. This was many years ago, but the point is that there are many entry-level jobs where grasp of language is not so important, and EU laws are very amenable to migrant labor.

You may be picking grapes, or loading trash bins into the trash truck, but you'll probably be able to find some job where language skills are not required.

Incidentally, it's gotten much harder to do this as an American than when I did it, but as an EU member citizen it should still be easy. Plus, that's just the EU. OP didn't say what they wanted to learn. How easy this is varies from country to country, but the fact remains: it's still the easiest, fastest, and cheapest way to pick up a language.
