I have a former classmate who is in the University of Arizona doctoral program (SLA and Teaching) and highly recommends it. They have a few different tracks within the program, so hopefully you can find that right niche.
Sadly, no interview. That alone leads me to strongly assume it's a rejection, but without any contact it's hard to really know what's going on behind the scenes.
Still waiting to hear about the Educational Communication and Technology PhD. I've received no news either way yet, which feels like an implicit rejection...
