Most hiring by most companies is not based on research. There is a huge body of research on how to hire effectively, part of the filed called industrial and organizational psychology, that goes back a full century all over the world. There is also a lot of legal regulation about what can be done and what cannot be done in hiring procedures. I wrote a FAQ about this issue a few years ago that lives on as a well liked Hacker News comment[1] that I welcome you to check. The FAQ links out to a lot of useful online resources about the research and law on hiring procedures.
