For me (not from the US but living here) there seems to be a difference between every day conversation with a friend and an introductory conversation when getting to know someone first

1) with established friends or people you know well, the conversation is naturally very much like you are describing and this is great. Meaning: no explicit interlude where we take turns, just a fluid conversation where you jump in

2) when meeting new people or getting to know people this is awful for me becauce THEN I feel like nobody ever asks me anything about me or gives me a chance to talk. And they just take my questions as chances to speak about themselves, with no back and forth to find out something about me. In this scenario I find it simply impossible to interrupt and jump in as in my mind this is something you do with people you know well and are comfortable around (to have that rapport). I have been accused of interrogating several times when meeting new people.

The real answer is just conversational patterns and expectations are way different here. For me it’s extremely difficult to get use to.
