I used to hate being interrupted. Then I travelled and realized in most places where I don't get interrupted, I simply... cannot talk at all!
I find that people who are used to be in environments where it's impolite to interrupt develop strategies to be always the one speaking: speaking fast and without pause, never letting the space for the other to say a word etc.
So I learned to prefer people who interrupt. The difficult part is for you to learn how to interrupt, but then conversations can happen.
In 'no interruption allowed' environments, sometimes I'm so pissed I do interrupt (or try!) But the other person continues to speak over me, louder and louder, because they feel entitled to do so because they are not the one who disturb the convention.
Obviously, in an ideal world, it would be better if people were not interrupting AND letting the other speak, but I can't say it's the most common case...
