Apart from the HR the people who interviewed were very unprofessional. They are not aware of the position you are interviewing. I was told to present a business case as my third round and the interviewer was not aware of my topic. She didn't ask any question on the slides, probably she was not knowledgeable enough to understand that. Through the interview she was distracted and making gestures to some one in the house. I have a very bad impression and about the company after this as I strongly believe in professionalism and showing respect to the person who is investing time for a disorganized company like this.
