Great interview - Totally agree with the need to write nice and clean code, less time debugging, less time figuring out what the heck some else's class/module is supposed to do, etc... Although I agree that in reality it doesn't always happen as bosses don't appreciate the shear amount of effort that goes into a software project - they just want it done as quickly as possible just so they can make money / look good in front of their boss etc...
One thing I like to do is look at all the software projects I've done in the past and group together all of the common functionality and then create nice clean class wrappers that handle the functionality that all of the previous solutions used.
