FINTRX Business Development Associate interview questions

Someone reached out to me via LinkenIn and asked me to do a phone interview. I did, and it was average. At the end of the interview, the interviewer told me that I would hear in two business days. After two business days, I emailed asking for an update. Two weeks later, I still haven't heard. I think it is incredibly rude of them not to said a quick email saying yes or no, especially when I asked for an update and when they claimed that they would reach out even if I did not get the role.
