I couldn't agree more. Most interviews assess your ability to interview well, not do the job well. Stanford even run a class on the software engineering interview! I'm currently working on a product to help companies to build realistic interviews, and I'm seeing some other startups focus on this too, so hopefully it will become a thing of the past.

The Stanford course, for the curious: https://web.stanford.edu/class/cs9/
