Then when they apply for the job you give them the equipment and watch them do it in real time. Inspect their results. Give constructive criticism and explanation as to why this or that is important - then watch them do it again.

This sounds reasonable which is why you are not allowed to do that any more. At least in the states you are not. You can get sued at best and hauled into court on a variety of charges at worse. Lose your business license.
