The effectiveness of various hiring methods has been demonstrated pretty rigorously now. But how many companies now take them into account, neverminding 1924?

The effectiveness of various hiring methods has been demonstrated pretty rigorously now. But how many companies now take them into account, neverminding 1924? I'd probably be more expecting a Belbin or Myers-Briggs questionnaire to be required, than a work-sample test, to have my suitability tested for certain roles, despite the established effectiveness of various methods. Great post btw, in the link.
