Mirasco interview questions

I applied online and was asked to come in for an in-person interview. Showed up and no one was at the front desk. I had to call the HR lady, who seemed annoyed I called to tell her. We sat down and the interview went well. She later told me that she would send a behavioral quiz to take as the next step. I never received it and I followed up and never got a reply. I find it very unprofessional to no respond to a candidate. If you are not interest, then state it.
