Xchange Technology Group Inside Sales Position interview questions

The first phone interview was scheduled by the Human Resources assistant to have a phone interview with the Director of Human Resources - no show. I took time off from work to conduct the interview in the privacy of my home. I reached out to the Human Resources assistant to inform her that I did not receive a call from the Director of Human Resources to conduct the phone interview. The Human Resources Assistant once again rescheduled the phone interview (second) time for me. I was prepared once again to conduct the phone interview with the Director of Human Resources and again no phone call - no show. I received no correspondence by phone or by email to inform me of any cancellations of the first and second phone interview. I had to reach out to the potential employer. This behavior is unacceptable in my opinion and speaks for itself in anyone wanting to pursue a professional career within this organization structure.
