In all my years (20) as a network engineer we have ALWAYS been able to screen our prospective techs. It is called a hands on technical test, obviously they have never heard of this process. Weeds out the liars very quickly, especially if they take two hours to figure out how to change the desktop backgound!
You don't just give a tech a try, that will fail 100% of the time. Sounds like this company is just like the Geek Squad, yuk!
