Royal Food Service interview questions

My interview was scheduled in a timely manner. However, once it was time for the interview to start there was no manager to interview me. I received a call from the manager 30 minutes later explaining that there were technical difficulties on their end and that we could reschedule the interview. I reached out to HR and the manager directly on more than one occasion and received no response from either. Overall, the interview process was very unorganized and unprofessional.
