While this article is mostly fluff, I question the comparison to a "farm team". Few players from farm teams ever make it to the big leagues. Assuming the comparison is similar in this case, what happens to the tech workers who have just invested a year of their lives learning some proprietary stack and incorporating themselves into a company's culture and get let go because they didn't make the cut? That won't look great on a resume. Also, what metrics will they use? Will people move into permanent positions based on performance reviews? Hopefully they don't apply the same old-hat ideas to these groups and try to rethink how they grow their teams from the ground up.
Also, I'm not really sure how this differs from hiring interns to test them out before going full time? It just feels like the same thing with a snazzy name.
