in too crucial a role in hiring procedures. Don't screen out people on the basis of biography until you know what they can do for you. A job applicant's biography may possibly tell you what the applicant did for other employers, but it is a demonstrably low-validity way to find an applicant who can and will do a lot for you. The best hiring procedure is to give your applicants a work-sample test.

But the bottom line is that most companies in most countries use stupid hiring procedures, because their managers are too lazy to do even elementary research on the HUGE prior literature on what hiring procedures are most effective (and most legal in countries that have laws about hiring procedures). In the United States, if you are looking for the "best candidates for jobs" that the submitted article here talks about, you had better be using a work-sample test as part of your hiring procedure.
