Kuder interview questions

I had two interviews, one with HR, one with two different managers, both of which seemed to go very well. At the conclusion of the second interview, I was told they had others to interview but I would hear something early the following week. I followed up the next day via email, thanking them for the opportunity for discussion and expressing my interest in moving forward. I never heard from them again, ghosted by HR. It's fine that they weren't interested, but they didn't even have the decency to let me know.
