Hey Minoos, I'm a first year at DMU. Honestly your stats are a bit low but you have an interview so that is very promising. DMU doesn't waste time on interviewing people they aren't interested in. The day will start out with meeting the Dean, people from finacial aid, a couple of the OMM fellows, and some other meeting I can't remember. Then you will have a tour, probably led by a first year student. Then you will have lunch and there will be a number of current students at lunch to answer questions and tell you more about the school. Then you chill out till your interview. It should be one or two Phd's and a student. They will already have reviewed your application and developed questions based on that. The interview last about 15 to 30 minutes. It is very relaxed, but you will probably still be nervous. English not being your first language is no problem at all, I have a number of classmates who have English as a second language. I hope that answered some of your questions. If not, feel free to ask.
