If they don’t pass FizzBuzz, you try to teach them for 6 months until they do fit into your company.

Is that so hard? Training on the job used to be common, and for entry level positions it should be possible at least.

EDIT: Okay, maybe not FizzBuzz, but the lots of "10 years experience with Angular 4" and co at least, and in general sometimes testing people more on actual tasks than on invented exercises. Even in Germany in the first few weeks you can terminate employees for any reason, so you don’t need to be too selective with hiring.
