I'm sure this happens, yes. But, that's not what's going on here, IMHO.

Asking a person to traverse and modify a linked-list (a very common problem) or to implement a B-tree are not 'tech outside their job'

Most of these interviews are more like math problems than anything a practical developer would encounter.

Shit, if these interviews were "What do you think of node?" or "What is Go's concurrency model?" I think experienced people would do fine.
