The stuff tested by a coding interview won't get to staff level or beyond. Cross functional understanding, product or technology insights, strategic thinking, etc. are necessary.

Lots of people who come up through the ranks only know how to do coding interviews - coding is what they do in their job, it was the interview they passed and it is what they know in depth. These are also the people confused about why their careers stall.

I never used coding for interviews at Google - even for junior engineers I wanted to see if they understood issues beyond their fingertips. Of course there was always a coding interview or two, so that base was covered.
