I'm not sure about introverted. I am, but when I get excited about a topic, I can be as loud as the next person. As long as I feel I have something to contribute, that is. I can rant for two minutes straight and then suddenly and unexpectedly shut up when I've made my point. People are sometimes surprised and ask why I suddenly stopped talking. I'll answer: "I've made my point."... :3

So my bet is on error avoidance.

I'm pretty similar, but solving a bug in an interview question is hardly something I'd get excited about.

I agree. Still, the point I was trying to get across is this: While introverts do not strive to take center stage for its own sake, they are perfectly capable to do so for any good reason. Introversion is not shyness.
