You already have a basic gist of what this position entails after reading the job description (at least you should). But, it's important to remember that the formal description really only tells you so much. Often, those paragraphs are recycled year after year, without ever being updated to reflect staff changes, shifting responsibilities, technology updates, and other factors.

So, asking your interviewer what sorts of tasks you can expect to complete on a daily basis is definitely recommended in order to get the insider scoop. It'll give you some greater insight into the actual responsibilities of the position, as well as an idea of how the company, the department, and its team members' general functions.
