interview struggle

all of the interviews I have scheduled are over the phone, which is not a problem. the problem is that these people are so busy it's hard to find a time to sit down and talk. along with that, some of these people are not emailing me back to confirm dates or times and I am the type of person who likes confirmation and have plans set in stone. I like having a set work schedule, I like making weekend plans at least 4 days in advance and then they must be CONFIRMED the day before. is that weird??
