Certainly, and yes that is tree traversal, but we don't refer to it in that manner. We refer to this in the context of recursion and iteration. Our interview process for devops is focused much more on practical application.

Po-tay-toe, po-tah-toe I suppose.

I think you've hit on the exact issue here: it's not that anybody disagrees that their coders they are hiring need to be able to do tree traversal. The issue is simply that we have given a complicated name for something very simple that every coder already understands. It's simply a communication issue.
