Amdocs Development/Testing/Managed Services/Dev Support interview questions

First there was an aptitude test. Then there was technical interview. I was selected for technical interview. So, I joined the interview meeting at 10:30 am but till 12:00 pm there was no one to attend me. After this experience I wrote an email to their HR for rescheduling their interview, thinking there was some miscommunication but I got no reply from them. Later, I got an email from my placement cell that some people were selected for this company. These people wasted my time for nothing, I was sitting like a fool in a meeting that they scheduled.
