One former employer tested prospective hires by handing them a print-out of a script, nothing too fancy, just some shell script, and ask them to explain what the script did and if there were any errors.<p>If one can read the language, and know what it does, the errors are pretty obvious. If the prospect doesn&#x27;t know it, they&#x27;re not able to talk to it, and the bullshit meter goes off pretty quick if they try faking it.
