Qualitest Test Automation Engineer interview questions

I was called for the interview and the scheduled time of the interview was 11.30 whereas I was made to wait for more than 2 hours without even telling at what time the interview may be held. They did not have basic courtesy to atleast ask me to go have lunch and come and tell whether the interview would be taken post lunch. HR also did not behave professionally to intimate about the timings. They did not answer the calls when the receptionist tried calling them to check about the interview process. I had to come without attending the interview
