If you are expecting your interview process to be like that of you friends going into medicine, gen surg, or some other field, you can forget it. Basically, most places tell you when your interview is, take it or leave it. Some give you a choice of two and in rare cases three dates if you're lucky. Essentially, they know that if you can't make their date, there's about 200 other ortho hopefuls who would be glad to have. They hold the cards, and they know it.
