has anyone had any experiences in trying to "cluster" interviews? by that i mean trying to group a bunch of them together when you know you'll be in the area, even when you haven't been formally invited. do schools get pi$$ed when you call and explain that you'll be in the area and are hoping that if you are being considered for an interview that you could schedule it for a certain time?? which schools are willing to help you out and which ones aren't? Thanks in advance!!
