Since this is your third time applying, have you reached out to any schools specifically to see what they think would be best to improve your chances? If not, I would recommend calling and admissions counselor at some of the schools. They are very friendly and will pull up your application.
Lots of applicants get interviews during October-November.
My friend from last cycle received one August interview invite and dozens of interview invite during October and November, and he got lots of acceptances!
Don't worry if you are not getting any!
