"do ERAU grads (tend) to get more interveiws?"
No, they don't. Where did you get that idea?
I went to Riddle and I can say that it does nothing more than check the "I have a four year degree" square on the app. That said, they have some internship ops and reduced mins agreements that other places might not have. In my opinion, none of that comes close to making it worthwhile to go there. But, in the end, you need to research it for yourself and make up your own mind.
