Maybe charisma is the wrong term. I've found pleasantness and willingness to communicate to be strongly correlated with engineering ability amongst those in the profession. Likewise, the worst engineers I've worked with all had major anti-social personality issues. The profession has always involved soft skills in my experience. When I've hired people I designed small tasks similar to the actual day-to-day work they would be doing, and that filtered out candidates who lacked coding ability quite easily.
