I agree with your description for senior devs, technical managers, and above. But in my experience there is no reason such a burden needs to be a core part of a mid-level team member's job description. To be clear, explaining your work is a part of every developers job. But top notch presentation skills don't need to be a part of it. Developers can talk to other developers in sub-optimal ways that are still effective. But when your hiring process has an hour long presentation as a part of it, you are optimizing for the thing that is very likely not the most important feature of the role. The point is to structure your hiring process such that it optimizes for the right things for the role.
