Tokenadult isn&#x27;t around to chime in here, so I&#x27;ll take his place today. Hunter and Schmit did a meta-study of 70 years of research on hiring criteria. [1]<p>There are three attributes you need to select for to identify performing employees in intellectual fields.<p><pre><code>  - General mental ability (Are they generally smart)

  - Work sample test. NOT HAZING! As close as possible to the actual work they&#x27;d be doing.

  - Integrity (The first two won&#x27;t matter if the candidate is a sociopath).
</code></pre>
This alone will get you &gt; 65% hit rate. [1]
