I had colleague that was 10x developer but 0/10 communicator, if he didn't receive separate first message with "Hi, how is it going?" without me waiting for his answer before requesting something, he wouldn't reply.

It was such a dead end for getting things done (he was productive on his things, but blocker for everybody else.

I once worked with someone who got visibly frustrated when people didn't stop in the hallways to listen to her lengthy response to the phatic "how are you?" expression. She treated it as a genuine question.

It was a weird hill to die on.

That can be cultural. In some places that phrase was typically only asked, if a truthful and lengthier response was desired.

If that wasn’t desired, the greeting would be more like “Good day” or “Hello”.
