Similar experience - interviewing for a DBA position, one candidate couldn&#x27;t answer the most basic questions, started getting angry and not at himself.  The interview is clearly a waste of time so soon I&#x27;m saying &quot;thank you for your time today&quot; and he starts shouting how he is a good DBA, just ask his friend Mike, call him right now.  I reach for the phone, but not to call his friend Mike.  He left before security could get there.
