People showing up to interviews drunk or high, clear untreated mental health problems, etc.<p>One guy showed up hung over after walking a few miles to the interview after he wrecked his car the night before while out binge drinking and drunk driving.<p>I had one large guy block the exit from the interview room and demand that we hire him to do GPU programming, even though he clearly knew nothing about the subject. We said &quot;sure&quot; and then once he got out of the way had security come and remove him.<p>You really never know what you&#x27;ll encounter when you call people in for a chat.
