We deal with the issues brought up by others that most developers can't really do this, by asking them to bring a piece of public code that they like and give 10 minute presentation about it. The code that they select tells a lot and is a great starter for further discussion and finding out about how they think. It also demonstrates an essential skill, and that is evaluating other peoples work and how to work with it rather than against it.
