Sometimes the person conducting the interview is less prepared (or even more nervous) than the candidate. They might forget to give you the information you require to know whether you would be a good fit. You want to be sure you are well aware of a typical workday and ask them what kind of person would make their ideal candidate. Asking them about what they're looking for is a great way to assure them that you have those attributes and skills so they are left with a positive lasting impression.
