To piggyback on what others have said, if you're in a certain type of company then interrupting you to talk is an important social status symbol. It's an implicit (and sometimes explicit) signal that their status is greater than yours, and your submission to them is more important than the value you create for the company.

If this is the case, I'd highly recommend finding a place that values your productivity.

Isn't ignoring someone who wants your help showing that your status is greater than theirs?
