For most companies, the organizational cost is too high.<p>There&#x27;s a cost (in terms of time &amp; money) to onboarding someone, integrating them into the company and team, and getting them to be productive. That&#x27;s a reasonable investment for a long term gain, but for a short probation, it rarely pays off for the organization. The churn itself just isn&#x27;t worth it.<p>Moreover, it means the candidate is in an uncertain state. Should they keep interviewing if it doesn&#x27;t work? Should they change their lives and relocate? Etc.
