I'm in the same boat, trying to recruit is nightmare. I've got up to 3 positions available so I called 12 candidates yesterday, only 4 answered, one spent more time telling me about all his health issues and why this job wouldn't be suitable, the other 3 I'll interview on Monday. That was from an original pool of about 50 applications.
I left messages where possible with the other 8 but no return calls so far.
