I think people sometimes takes recruiters words too literally, wanting proficient in a language is a good way to scare of people afraid of leaving their box (I&#x27;ve met plenty of developers reluctant to try new languages and technologies).<p>Talking from personal experience I&#x27;ve rarely ever been more than slightly familiar with the language &#x2F;required&#x2F; for a job and I&#x27;ve always made this clear however I&#x27;ve also explained that this isn&#x27;t really a problem and I&#x27;ve never been rejected from a position because I weren&#x27;t familiar with their arbitrarily chosen technology stack.<p>Quickly acquiring new knowledge needed for the job is the most defining quality for engineers&#x2F;developers.
