If the talk turns immediately to formatting issues, that's not good. Amusingly, however, I've noticed that bad/newbie coders tend to indent stuff all over the place and have no consistency in the whitespace (this is C++ so the compiler doesn't care). Often you can tell the code is bad because it literally looks bad. I prefer the suggestion commenter 'John' gave rather than the OP's: "Can you draw me the architecture of your most complex project?"
