Plus remember that the interviewers are people too - maybe there is a personal problem that causes an off day, or a great day for them. Some are also better at interviewing than others. Also, maybe they really do think your child would be good for that school after the interview, but when all the applications are in they can’t accept everyone with your child’s profile (gender, geographic, academic level, sports, etc). DS is applying to college now, and at many schools we think he would do well if accepted and attends there, but may fall into that middle pack of kids who are all qualified, would do well, etc. but the school can’t accept them all. And if you put all those applications together and had AOs look at them maybe the yes pile today would be different than the yes pile tomorrow. Good luck with the process.
