QL design?

So, I submitted a resume for a curious job posting which was hilariously vague. "Looking for Visual Basic, VB.NET, or VBA coders!" I got a call this morning, "I know it seems vague, I don't know what to expect either, but the manager is looking for .NET experience and QL design." "Did you say SQL design?" "No, it just says QL..." I did not pry into it, but This Wiki page seems to be a QL, but I don't see how a Java language would work in a .NET environment. Help?
