I submitted my EA application towards the end of October and haven’t received an interview request. Considering the fact that I live in a fairly rural part of the US, I always suspected that an interviewer may not be available in my area, but I’m still a little stressed about it none the less. Does anyone know if not receiving an interview request is a bad sign? I would really appreciate any insight!

You need to take Admissions at their word.
@jmar98 - like ^ said, no need to worry, but just check your spam folders to make sure you did not miss any interview request email. In a different thread, a parent had posted that they checked spam folder 2+ weeks after the interview request (different school) had arrived and stuck in spam folder.
