It's not about whats broken, its about what you DO when it is broken.

This my favorite interview question to ask candidates:

"What is your all time biggest screw up, and how did you come back from it" - I then tell them the story of me loosing several hundred thousand dollars and the funny things that happened around it to set the tone. If you have been in tech for any length of time you have one of these stories (if not a few). I have heard some great ones by simply asking and it gives great insight into a candidate (humor, stress response, the things you have seen).
