When do interviews stop being offered ?

I haven’t been offered an interview yet for my top school. I live in an area where there should be a lot of alums. It has almost been a month since I submitted my application. I am worried and kind of upset that I haven’t heard from them. Does this mean that I won’t be getting an interview?? When do ivy leagues stop offering them, if my potential interviewer is busy with other interviewees?

Thanks

First week in February last year seemed to be the end.

D got into a number of top schools without being offered an interview. We live by a major city.

A friend got into a HYP without an interview and he was not that special that he was an obvious yes.

Thanks, seekingpam. My D was getting worried too.
