Advanced Medical Management Administrative Assistant interview questions

I applied online and had an interview after a week. There were two tests upon arrival. One asked about basic medical and math knowledge, The second test was a behavioral test. I then had an interview with the hr manager and her assistant. They told me they would get back to me in 5 days but they never did. When I emailed and called back, both messages I left were ignored. It was a negative experience because of the unprofessional rejection. A call or email back would have been sufficient instead of ignoring the messages.
