As somebody with decades of experience myself, I have never experienced anything like you describe. The "skills" involved in whiteboard interviews I've participated in generally consist of "writing code", "thinking through a problem", and "communicating about your process". A more intense interview might also involve skills like "understanding computational complexity" and "making reasonable order-of-magnitude estimates". It is difficult for me to imagine how someone could work as a software developer without using these skills regularly. Then again, I never took any "algo class" or any other CS classes, so what do I know. I just think people fret way too much about getting all the details right in coding interviews, because in my experience (both interviewing and being interviewed) that just isn't the point.
