I like this comment. A typical surgeon earns a bachelors degree, then attends medical school, before finally spending three to six years in a residency program (in the United States). This is before becoming a practicing surgeon. Unfortunately, there is nothing similar (in the United States) that is related to software engineering -- though many here would like to see something similar to an engineering license for technology professionals; there is nothing currently on the horizon (that I know of). In some ways, I think that Codility can help with this state of affairs. This is particularly interesting when we consider comparing metrics for education and experience; and perhaps 'real-world' success. The Codility statistical comparison, taking these factors into account, would be very interesting indeed. And could possibly result in data that furthers the state of the art in general.
