I hire and manage software programmers.<p>In the majority of cases the best candidates are those that &quot;code for fun&quot;. This means that they build shit that they find useful, interesting or to showcase a particular skill or new technology. It would be trivial for them to make some of this work available for me to see.<p>Where this work isn&#x27;t available we pay potential hires to work on something for a couple of days.<p>There is usually nothing on a CV that will convince me to hire a person over and above actually seeing some of their work. In cases where I&#x27;ve skipped the &quot;show and tell&quot; step as we call it, my chances of making a bad hire increase exponentially.
