I had no engineering background (education actually) and I was interviewed at Carle. Just be interesting. Really solid app overall and a decent school list, just a tad top heavy. I think adding in more mid-tier schools would be good for you. Try to get programs all across the country, both public and private. Some examples would be BU, Brown, Dartmouth, UCSD (your research may fit their needs), Pitt, some of the UTs, Wisconsin Madison, etc.
