I got an interview invitation directly from a professor in the program.

Applied math undergrad. They got back to me very quickly after I submitted. No financial info yet. Didn't take GRE.

Application deadline December 1, result 6 months later.

Was nominated for a fellowship early in the year, results got delayed to early April and then I found out I didn't get it because of budget cuts. Then I emailed a few professors, found one that wanted to work with me, and he put in for my admittance. The university froze admissions for over a month and I finally got accepted on 5/30. The grad program coordinator was very helpful, so if you end up in a similar situation, definitely reach out to her.

Got an interview in January. Then, during the interview, I was told I might get a visitation in a week or two. I didn't hear anything until my rejection in June!
