Your &quot;see-also&#x27;s&quot; provide good perspective.  It&#x27;s not just legal.<p>Some of the situations you identify (dating, friendship, sales, as well as interviews) have the attribute of &quot;found nothing compelling&quot;.  There was no single problem, but nothing emerged in the package or the interview that stood out.<p>In this case, the lack-of-match is not obviously the candidate&#x27;s fault, and trying to provide feedback is forcing a conclusion (&quot;that&#x27;s your problem right there&quot;) that isn&#x27;t justified by the information gathered.<p>And the best thing in such a case may be to say nothing, because you know nothing.  (&quot;Whereof one cannot speak, thereof one must be silent.&quot;)
