I wonder if the OP has ever read any actual research on effective hiring practices. I have a FAQ for that.[1] The short answer that research gives is to set up an actual work-sample test for the job in question. The longer answer is to add in a VALIDATED test of the worker&#x27;s general cognitive ability. But if that kind of test isn&#x27;t validated, the employer can be subject to legal consequences in the United States if the test has &quot;adverse impact&quot; on protected minority groups. Rather than just making up hiring procedures, companies ought to do research on what works for finding better workers and what is not legally risky for the company.<p>[1] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=4613543" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=4613543</a>
