The results suggest that women don't advance in their careers beyond a certain point without learning to interrupt, at least in this male-dominated tech setting. I don't see this. I see that as a person acquires more status they a) feel more confident in interrupting, and/or b) others are more lenient in allowing them to interrupt. I think one would have to follow someone over time as they move up (or not) to see if their interrupting contributes to advancement or is a side-effect of advancing. That said, I have a gut feeling that to get ahead you need the ability to persuade, and often this means interrupting to make yourself heard. But, more generally, people need to watch to see what is an effective style for their environment and learn it, and not just cargo-cult certain behavior.
