Etech Software Testing interview questions

I got a call from HR and it was like any other initial telephonic discussion. HR was like she is the best in the world and has a very unrealistic and seems like was forcefully trying to speak in american accent, which was very much HR types and had a very bad tone and approach & attitude. Most important she never introduced herself nor about the company. The interview was scheduled for next day 4:00 PM, but now there was not email communication about the same, I waited and waited, but no call received, when i tried calling the number it was not reachable, the next day I got in touch and again it was scheduled for the next day 4:00 PM, but again nothing happened.
