If the interviewer want to know if someone can write code at all, then why he/she expects much more than that in an interview?

I believe there is no single declaration about 'what the interviewer' wants.

Especially that several times they do not know themselves, just try to mimic what is expected from them or seen in some random situation they came across. Sometimes, of course.

"brining key stakeholders into conversations at appropriate time"

This is some very good quality euphemism here, two thumbs up! : ))
