NCR Corporation Test Automation Engineer interview questions

It was a face to face interview. But it was not started on time. They have kept me waiting for more than half an hour. After that interview last for one hour. The way of treating the people is very bad. They will make you feel that they doing some kind of charity by giving you job. Don't have professional ethics, no proper management. After completing the first interview they asked me to wait outside for HR round. They kept me waiting for almost one hour and when I asked the guard at reception "how much time it will take?" then he replied that our HR is not here. It will take more time so you can leave. What will be your reaction when somebody kept you waiting for one hour and tell you that you can leave. Finally I just asked the guard "can you please call the person who took my interview and ask that in how many days I'll get the reply from your side" and the guard without calling anybody told me that may be in next week. So you can imagine how was the entire process.
