Deep Silver interview questions

I have applied for the position on-line, Deep Silver HR contacted me within a week and asked for my preference regarding the date and time of the interview. I told her my availability and she didn't reply back. I waited until the exact date I suggested for the interview and reached out to her for any kind of confirmation or cancelling. HR said that she was still working on it, a couple of hours after that she did confirm, that I would have the interview. It was about an hour before the actual interview was supposed to happen. I rushed to set up everything and find a place to speak. Literally 2 minutes before the interview I received a phone call from the interviewer saying that she is stuck on a meeting and she would like to reschedule it for tomorrow. I agreed. THe next day I had been waiting for the call at agreed time and no one called. I emailed the interview asking if we were going to speak today and got an affirmative reply. She just said "yes" without giving any details about when it would happen exactly. She finally called almost one hour later than the scheduled time. It was obvious that she didn't have my CV in front of her and I am even unclear if she read it at all. She spent 5 minutes talking to me and then she said I was not the right fit and she would suggest me an alternative position. The whole process was unprofessional, showing any lack of preparation to the interview as well as any respect of other people's time.
