I haven't used them, but read the testimonials:

> ...sent us two profiles of solid candidates, one of which we hired!

> ...other recruiters sent like 50 CVs and we couldn't find anyone, and then RC sends a single candidate and we hired him.

How they do it: the Recurse Center puts more thought into collecting a small set of excellent candidates, then puts even more thought into matching them with employers.
