Thanks so much for your help! Also I have been listening to your podcasts for a couple months now, I find them so interesting and love them! Hope grad school life is treating you well!
Hey Kamille,
For the schools I interviewed (all northeast), I had plenty of warning, around a month if I am remembering correctly. I was given dates the interviews were being held and could choose what worked best for me. Many schools have a group of interviews in the morning and a different group in the afternoon, then lunch all together. Probably depends on which schools you are applying to. Let me know if you have other questions!
