Really? That sounds a little paranoid. I always just tell the truth on the interview and application. "You asked for 5+ years experience, but I only have 6 months. I'm willing to learn if you are willing to train me".
How many applicants will be inspired to lie because of my absurd requirement on the job spec? Of those applicants, how many will I hire? Do I only hire applicants who have lied in order to be protected so I can later fire them? I wouldn't hire someone who lied on their application in the first place!
