Epsilon QA Analyst interview questions

Interview was scheduled for 11AM on weekday and i reached there at 10:00 AM (an hour before). Just to give entry in their office they took half an hour,finally i got entry at 10:30 AM. then me and other candidates for QA profile were sitting there almost for 3 hours but not even a single interview started for QA profile. Everyone was asking you guys will start interview they replied we don't have panel for QA profile, if you want to leave for the you can leave . Almost 50% candidates left.I was still there as i already wasted my half day for this interview and asked if really they are going to take interview or doing joke with us. then HR said 2pm surely will start interviews. Finally they started interview at 3 pm, only one panel was there to take interview and took 15 min round for each candidate. My turn came at 4 pm. interview was very easy,even any fresher can clear the round. they said will get back to you tomorrow. but they didnt respond. I was in touch with other candidates...no one got any feedback from them..not even a single candidate..
