Said colleague is pleasant and harmless enough but is very very loud and talks constantly.
In team meetings, which we have on a daily basis, the colleague dominates the meeting and it literally is not possible to get a word in edgeways.
I have spoken to our manager, who is also in the meetings and he said to just jump in and speak as soon as the colleague has finished talking. Only problem with this is, if anyone else speaks then the colleague will start talking at the same time, and being louder will just dominate again.
It is not all work related chat, mostly just inane drivel.
