As a frequent passenger on Southwest and friendly with quite a few of the Southwest employees from baggage handlers to pilots I can confirm that I have never heard one of them say a bad thing about Southwest in fact if any thing they sing its praises.
As for their recruitment policy they no longer require a type rating for interview. They are happy to interview otherwise qualified candidates without a type rating and if successful at the interview they will give you a conditional job offer. The condition is that you will have to get a type rating before you start.
