&gt; &quot;We’ve seen that most engineers only have the stomach for a limited number of interviews. Investing time in the wrong companies carries a high opportunity cost.&quot;<p>I suspect in addition to not having the &quot;stomach&quot; for an unlimited number of interviews, they don&#x27;t have the vacation days to burn for them. Let&#x27;s say you are working already and have 10 days a year vacation (pretty standard). With these ridiculous all-day interviews, you have the ability to waste that vacation on a maximum of 10 companies, and that&#x27;s if you choose not to take any &quot;real&quot; vacation at all during the year.<p>In an environment like today, where every company is ostensibly hiring yet overly picky, a job candidate potentially will waste their entire PTO balance on interviewing with companies serious about interviewing but not serious about hiring.
