I got my first CFI gig through a lead given out on an aviation forum. So it's not all garbage and every once in a blue moon you actually network and exchange information with other professionals.

Anyway back on topic. One of the recruiters told me that the January class was filled awhile ago and only has 10 candidates. He also said they're ramping up in Feb with a class of 40. This information is about 6 weeks old though.
