Omega Healthcare Senior Java Developer interview questions

They had scheduled my interview on a Saturday and asked me to come by 11:00 AM. I have reached there by 10:45 Am and was asked wait at the reception. I waited in reception till 2:00 PM then HR called me and inform me that interview panel is not available and will reschedule it on Monday as a telephonic interview. I said ok and moved ahead. Then on Monday morning another hr called me and asked why you dint appear for the interview on Saturday. I explained him that I was available but the interview panel was not there. So he said he was scheduled a call by 5 PM and I said ok. But I dint get that call as well. Total waste of time.
