HARMAN interview questions

I had received a call for telephonic round on 22nd June, 2017 from the HR and she told that this position is for Pune location. She scheduled the same on 23rd June at 8.30 pm in the evening. So, I was waiting for the call but I did not receive any call. So, I mailed the HR after 15 minutes of waiting. But I did not receive any response. Then, I mailed them again at 9 pm. Then I received the mail from HR to wait for 5 minutes. But after waiting for again 30 minutes, I did not receive any mail from HR. So, I mailed her to schedule tomorrow i.e. Saturday. On Saturday, she scheduled the same at 1pm but I did not receive the call again. So, I waited for 30 minutes and called the HR for the same and after waiting for half an hour, she told me that she will schedule the same on Sunday. So, I told them to schedule the same after 4pm. She was again okay with the same. But I did not receive any call on Sunday. On Monday, I called her for scheduling the same, then she told me that she had already scheduled the same at 4pm. I told her that I am not available at 4pm and schedule the same at 7.30 pm. A person named Viruprakash called me at 5.30 pm and he was sorry that he did not call me at 4pm. I was confused totally. How Harman HR was managing people in their company. I told this guy to call me at 7.30 pm in the evening. He was okay with that. I informed the same with HR and she was surprised to hear the same. Then, the time for interview has come. Viruprakash called me at 7.45 pm (late again). He was in hurry to go somewhere, so he finished up the interview in 6 minutes only. This was the shortest time I had gone for the interview and the questions he had asked was of some different level. How do you rate yourself in Core Data Abstraction in Objective C is possible or not: Yes NsObject is an abstract class: I was confused about this answer because you can override the methods declared/defined in NSObject. Nsobject is root class: Yes He asked me is there any superclass of NSObject: No touchesbegan method is declared in which class: UIResponder (who will remember these things). UIbutton hierarchy weak and assign difference PerformSelector and normal calling the methods He was in so much hurry that he was not listening my answers properly and also, trying to confuse me by using sarcastic comments. Now you can judge how much professionalism these guys have and how will they work in their company.
