I’m an Engineer, Not a Compiler
Imagine interviewing carpenters:Method 1:  How many ten penny nails in a pound?
  Who makes better screwdrivers, Craftsman or Snap-on? Why?
  What's your favorite toolbox? Why?
  How can you tell when wood has been treated?
  Why should you measure twice, cut once?
  Which end of the hammer do you hold?

Method 2:  Show me something you built. Describe what you did.
  Cut this piece of wood according to these specs.

If you needed someone to build your house, which method would you choose?
