What I have observed, as more and more people from a wider background enter into computer science and software engineering, is that it's not so much what they know or don't know that matters, but rather, what is their attitude towards learning something they don't already know. If they embrace new knowledge and appreciate those who bring it to them, then I couldn't think of someone better for this art. If, on the other hand, they dismiss anything that they don't immediately see the value to, even at the behest of someone either more senior or experienced, then I would say, that is the red flag.
