Recruiters keep asking me my top three technical skills. Let's see if I can figure it out -- here's an unordered list.

Object-oriented design and programming
Specification-oriented interface design and implementation
Disciplined software engineering: checking for and reporting error conditions with useful error messages, meticulous use of version control, commitment to clean design
Taking advantage of language and library features
Tracking bugs and odd behavior to their source by reading code
Finding, evaluating, learning, and using new tools: libraries, applications, utilities, books, tutorials, etc.
I don't think these will make much of an impression on recruiters, but I think a programmer would appreciate this list. Any suggestions?
