Udacity and other online education platforms still face a lot of skepticism from within the technology industries they target. A common refrain is that they’re unproven. There’s some standardization as to what a college class or college degree means in terms of effort put forth and comprehension gained, but a Udacity “nanodegree” or Coursera specialization track is still a question mark for hiring managers. A sentiment I see on discussion boards is that MOOC coursework shows interest in a topic or field, but not necessarily proficiency.
