I'm hiring and I'm fucking done with recruiters buttering up skills etc and sending me BS candidates.

Interview earlier today...
CV: MySql skill level 10 (out of 10)
Reality: Can't write a simple JOIN!

Yesterday...
CV: PHP 6+ years exp, self proclaimed ninja/jedi/oracle.
Reality:
[Me]: Write me a function to map an array to x.
[Ninja]: What's an array?

I've come to the conclusion that the type of dev I want on my team is highly unlikely to be looking for work much less using some piece of shit shady agent to find work so I need to hunt him / her down personally and can use the phenomenally large recruiters fee as a hiring bonus / incentive.

Only problem now is finding quality full stack devs in the area (Johannesburg, South Africa).

I'm thinking of posting a 'challenge' job add to filter out good candidates - some kind of code challenge to be solved that gives them my contact info. Any one have any creative ideas I could try?
