"So wait you are smart enough to get into caltech, smart enough to graduate with a degree in CS. And yet the curriculum on its own does not do a good job enough on its own to prepare you for getting a job?"

This was my first thought too. A course just for passing interviews seems odd. We had two small activities that were part of a business course (business administration minor), but after hours. One was a mock interview to give you feedback about professional appearance, not fidgeting, etc. The second was a mock business dinner to provide feedback about etiquette, customs, etc. These were valuable, but they focused on soft skills that aren't covered in the regular course content.
