Anne, looking at your credential, I wonder are you sure you want to come to ND not MIT or Princeton?
Julie always mentions that some students are better off going to a MBA or a MSF program. If you really want ND you should write to explain your career goals to them.
Don't worry. my application was on hold for an entire month before. But I was admitted eventually. It is not rejection. btw, i applied for notre dame two years ago.
