Rockstart interview questions

Had a 30 minute interview which was supposed to be followed by another round. This was confirmed for couple times by the interviewee during the call. However, never got invited, without any communication from the company's side. This ghosting took some time, after me trying to reach them through different channels, I have received a generic negative response after a month.

I had an interview 2 years ago, both with hr and the investment manager. I asked multiple times about the status of my application, but I never received a response. I know they saw my emails and messages because I track them. They could have simply let me know with an email that I wasn't selected.
