Why in the world would I want to waste my time interviewing someone with neon bright blue hair, nose ring, who is into all kinds of weird stuff.
Should I risk company money for the off chance one of these might actually be gem?
If it walks like a freak and talks like a freak, it’s probably a freak.
The nose ring and you probably agree: bad match
Because you don't know the truth. Fact is, if they are more concerned about the job, they'll show up with normal color hair and pearcings out. You won't even give them the chance. And quite frankly, the "weird stuff" they are into outside of work really isn't your business. I realize you may want to use that in your decision, and that's fine, but again, precluding someone from the interview who, for all intents and purposes appears to be a decent fit for the job, based entirely on ignorant stereotypes that have been debunked time and again is just plain bad management.
