>I suspect even in Europe companies don't tell applicants why they didn't hire them.

They usually don't. The same reasons apply. In Europe there's less fear about random lawsuits, but there are so many rules about hiring that it's just a minefield with lots of material for very legitimate lawsuits. You didn't get the impression that the applicant is a good culture fit? You better hope his name didn't sound Turkish, or that quickly sounds like unlawful discrimination.
