Cywarden interview questions

First of all the HR called to schedule to the interview. I did pretty well answering almost every questions except one or two. I then waited for a few days but no response from them. After 15 days I called the HR to know the result. I had to remind her for 2 days to know the result but at the end she told they don't have the feedback of the interview so they will conduct it again. Again I gave the interview and went pretty well. Then after 3 days no response and again I called the HR. Then she told me they are not hiring for this position, if the need in future they will contact me. How unprofessional is this. Our of frustration my sister called the HR and then she told she didn't said that, she told I didn't clear the interview, also the position is on hold. Who can clear the interview then even after answering each and every question. Please don't waste your time here. There are some unprofessional people working here and you would waste your time like I did. Better go for some better company.
