RSM Consultant interview questions

First round was phone interview with HR. Second was on site interview with 3 people, from manager to partner. wait for two weeks to get an offer. whole process was very nice and people are friendly there

I met a company representative at my school who referred to me their hiring manager. I emailed the hiring manager and had a couple emails back and forth. Then, I went through a pretty standard phone screening interview where they asked me general questions. Everything seemed great until they ghosted me completely. I even tried emailing them again asking if I could know the status of my application (knowing full-well i was probably rejected), and still got no response. Pretty unprofessional.
