Don't forget that things are changing quickly, and what was true 18 months ago is not true now. If you don't keep up, your information is outdated quickly.
If Envoy is getting 50% of new hire AA classes, PDT is getting 25%, and PSA is getting 25% - that doesn't leave much room for people outside, does it?
What was true last year will not be true next year. Choose carefully.
I am not cheering for the AA regionals. I think that they are poorly run and underpaid. There are much better companies out there. But, know what is really happening at each, and in the industry as a whole.
