DaVita Operations Manager interview questions

I applied online. A recruiter contacted me to set up a phone interview. The interview went very well, so much so that the recruiter stated that I should be contacted by the hiring with in 24hrs. I never received a call. I emailed the recruiter, I got an email back stating that she was going to follow up with the hiring manager and let me know.... she did not. I email the recruiter again about 5 days later, this time I did not get an email back. a few days later I got an automatic rejection email. This was one of the most unprofessional interviews I ever had
