Interview invite after accepting another offer. Not going to accept interview, but help me make sense of it?

[taacc]

Hello everyone,

As the title suggests, I received an interview invite from one of top choice schools, after I already accepted an offer the other day for a program that I feel is a good match. And for context, I pretty much *just* accepted the other offer when I got the interview invite email from my top school, so I hadn't even had a chance to let other schools know I'm out of the running.

Of course, I stuck with my decision and rejected the interview invite, because it would be unethical not to. But this situation kind of left a weird taste in my mouth, because I wasn't expecting to have a chance with any of the remaining schools I was waiting on, especially given that it's already the end of March. I actually even contacted my top schools asking if they could tell me anything about where they're at with my application, as a way to show courtesy to the institution who extended me an offer. I guess I was hoping not to have to hear from my top schools after accepting elsewhere, and that my assumption that their silence is an implied rejection holds true.

Can anyone help shed some light on this sort of situation, or even just tell me about similar experiences? Does it occur often where schools are just starting their interview process this late, and what does it mean? Just hoping to chat about this situation because I'm confused, and have some mixed feelings to process through. On one hand, I think the offer I accepted was great and still love the program there, and feel good about the fact that I did the ethical thing and stuck to my acceptance. On the other, it just kind of stings a little that I didn't know, until it was too late, that my top choice program was even considering me to the point of getting an interview.

Thanks!
