PROBLEM: Person1: I am not sure what to do to get ready for my job interview .
Person2:Make sure that you understand the company . Do you understand what it is that they do ?
Person1: No , I probably need to do some more research .
Person2:When you've finished your research it will help you figure out whether your company is rigid in philosophy or kind of more relaxed . Does that make sense ?

Person1: I have absolutely nothing so far .
Person2:You know I could go shopping with you sometime if you need it , but can we talk about other basics ?
