&gt; Worse, in an exercise reminiscent of companies offering unlimited PTO, &quot;not on-call,&quot; when read between the lines, could really mean &quot;always on-call.&quot; I currently work with teams that operate this way, and the amount of burnout is staggering.<p>I&#x27;ve found the best way to screen for those sorts of problems is to ask everyone in the interview about their personal habits, instead of about process. Don&#x27;t ask about vacation policy; ask when&#x27;s the last time your interviewer went on vacation. Don&#x27;t ask about the on-call rotation, ask about what issues came up outside work hours in the last month.
