A decent interviewer wil have everything that could possibly be asked down pat for the interview. There are always questions you can ask, however. The best way to get the information for the questions that want to ask is to visit the company website. In this way, you can ask questions regarding the different branches/offices that may exist and if you will have the opportunity to visit them. If you will have any contact with them at all. If you will have the ability to cross train to other departments.

One interviewer I had actually had a typewritten list of any and all possible items of any relevance except for how long the particular office had been at the location it was currently occupying.
