This totally cultural. I am French, and when I was living in Spain, it was very difficult to get a full sentence out, but in Germany, I am often called out for interrupting people all the time (and I master Spanish and German at a similar level, so this is not related to language proficiency).
What I also noticed now that I try to pay attention to it is that I am practically unable to say a word in a German conversation if I try not to interrupt. I seem to be missing the cues that seem to say "you may now speak", and have the feeling I get interrupted all the time. I guess those cues are culture-specific and internalized over time.
That might be relevant to the OP 's question: in a multi-cultural team, one might need to develop a set of cues that are specific to that context. That can only come by discussing the topic one way or another, be it during the meetings, in breaks, at lunch... In my case, telling exactly what I described above, in a "aren't cultural differences interesting" way helped.
