You have a point. What I meant was I haven't used theoretical knowledge of data structures. Arrays and hashes does not count :) That's just basic programming knowledge. Whenever someone uses the term "data structures" I think about the inner workings of different types of B-tree's. And since I don't know the inner workings of the more advanced data structures, I would probably disqualify myself.
