If u try to interview with a big corporation, u should be aware of the following. First, u need to dress properly when u have an interview. You can google it and get some sense of it. Second, u should prepare your resume well, and it should be well constructed. (U can use MS word to find a template for it). In the interview, you should emphasize more about how your talents can actually help you handle the job. Such as, if u are interviewing "sales" , u should talk more about how you can communicate with others efficiently. Good Luck.
