Interviews and rejections

[Iio5590]

If a school conducts interviews and you do not receive an interview is it safe to assume you most likely have a rejection for that school? I want to remain optimistic, but at the same time I'm trying to be realistic. I already have an acceptance for a school so I'm not freaking out too much, but I just want to know what my chances are of getting into some of the other schools I applied to. That April 15th deadline is approaching quickly and I'm thinking if I haven't gotten interviews for my other schools, should I just plan to go to the school I got accepted into?
