Grand Canyon Education interview questions

I was invited to the call screening. The person doing the screening had to reschedule last minute which is understandable. Once I got on, one of the first questions she asked me was about my education which I answered truthfully. She said she would have to get back to me to see if that works for the hiring manager. Put the call on hold for 45 minutes until I finally reached out via email asking what's going on she told me she would get back to me. After going back and forth with her for 3 days trying to understand what education requirement I needed, since it was not listed on their posting as required but preferred, and showing I was met the minimum requirements, she completely ghosted me and did not respond. Extremely unprofessional and will not be looking to pursue with them even if they reach out. Waste of time.
