Amdocs interview questions

First of all, HR person called me to get information about me and scheduled first round. I waited for the call but no one called. Also, HR person didn't provided any contact info to contact them back. When I tried calling them back, it reached reception. After few days, they called again to re-schedule the first telephonic interview. The person called me this time. During the interview, I realized that the person who was asking question was really a junior person whereas HR told me that it would be the technical manager or senior person who would be interviewing me. Moreover, this person was not aware of correct answers himself. My first round went well. After few days, HR person called me again to schedule the second round. I asked to provide me her contact number or email so that I can contact her in case I need to. She promised to send an email to me with job description. But she didn't. The second round happened. Again, the person wasn't a senior person or technical manager. I answered most of the question with correct answer. After that, there was no call or feedback.
