ClinCoffee

Thanks in advance for your advice! I’ve received a clinical psych interview invite for School X that requires me to respond and confirm attendance by a specific deadline (the first interview invite I've seen that's asked for this). Multiple other schools I applied to have the same interview date, but those schools have not sent out invites yet, and, judging by past years, will not have by the deadline. I don’t want to be presumptuous at all about interview possibilities, but I’d rather keep that date open until those other schools extend invites. Key question: Do I have any other options other than confirming attendance at School X and then changing my mind (feels markedly unprofessional) if another school extends an invite on the same interview date?
