CNA Claims Examiner interview questions

It was not a pleasant experience. Did not feel the respect from the Company. I was invited to attend an interview with CNA Hardy. However, I received the HR's email on the interview day that something urgent happened to them and they were not able to attend the interview. The HR assured that he would call me back on the same day or next day for the reschedule yet I have never heard anything to date. My follow up calls and emails were ignored. Still have no idea of what happened to my application after the short 'interview postpone' email.
