I know two CS PhDs who would fit into the "can't code FizBuzz" without help. Both are machine learning/stats experts. Both also "code" in MatLab/R all the time.

I know two CS PhDs who would fit into the "can't code FizBuzz" without help. Both are machine learning/stats experts. Both also "code" in MatLab/R all the time. However, it would take a developer 5 minutes to realize they can't code shit. They are good at other stuff ... sure ... and they shouldn't be applying for programmer jobs. I think startups are trying to emulate the Google way of hiring and that is to their detriment. There used to be a time where Microsoft hired an MD/PhD to become a coder ... because he had raw intellectual horse power and a desire to learn. I know quite a few PhDs who would love to work for a startup. Most of them have gotten dejected after the interview process. The common complaint I hear is "interview made me think I'm going to be a code monkey. F that. I'll keep my cushy research job with a door on my office".
