Better typing, verbiage, and grammar skills would help. I'm really not trying to be rude, but as a business owner, I have to honestly say that I can barely understand the questions you ask here, let alone give you questions to use. I wish I could help, but without knowing more info regarding your interview, and not sure if your interview is in The States, or another country, there's probably not a whole lot anyone could do to help.
I suggest you ask your questions on Quora, but write them down first so others can understand what you're asking. Again, I'm not trying to be rude. I'm just letting you know that slowing down and typing correctly matters.
