How is this conceptually different than a course that focuses on standardized tests like the SAT? Having worked for only almost 2 years after college graduation, I can still see that there are many more technical and non-technical skills that affect one's and his/her colleagues' performance on the job. Being nice and helpful is one. Constantly learning from mistakes and rapidly iterating while adding value to the team/company is another. More examples: Picking up technical books, writing toy projects to learn new languages/frameworks/libraries and being able to come up with good engineering decisions. The list goes on. Not to be too salty about this, but I remember friends from college who are terrible teammates (no significant contributions to group projects, barely understanding the project material, but knowingly do so cause others will finish it for them etc.) but go on to get job offers from the Big Four. Having these technical whiteboard interviews will not filter for such soft skills that are needed to succeed in the workplace.
