I notice that you mention "computer scientists," "programmers," and "hackers" in your comment. Those are all different types of people, and generally not the kind companies are looking to hire. Most companies are hiring "software engineers." That is, they want people to build stuff in a team with other software engineers, things that are well designed and stand up to the various forces that software systems are subject to.

Ultimately, though, you're right. The problem is that software engineering interviews aren't actually about software engineering. And, that's what really needs to change.
