They want to understand how you got there.
Other people make the jumps with you, figure it out at the end, or just plain figure if they didn't get the connection, they didn't! :)

Seeing all sorts of different people, and not just different styles of writing, but the thought process that goes into it, coming together and hashing things out with each other!
