Here you want to get a pretty detailed explanation of how the candidate has used continuous integration on previous projects. Continuous integration is a set of automated build, integration and test steps that executes against the code base in a configuration management repository. For instance, if you were using Java and CVS, the CVS repository would have a set of triggers that automatically built, integrated and unit tested the code often, perhaps each night, perhaps a few times a week, or even every time someone checked in new code. Each of these is a valid continuous integration story.
