Management Consulting Question:

Sometimes this seems like a no-brainer. I mean why else would you be giving the interview right?
The thing is, most people don't know what they're in for when they choose to go into consulting. This is more so for students who aren't business majors. The employer wants to know if you really know the consulting industry. Are you getting in just for the money? Or because it sounds cool? Or you don't know any better?
Even if the above is true, you should appear to be a well researched individual who knows what he/she wants. A lot of consulting is about marketing yourself/your company/your skills - take your pick. And this starts at the interview level.
