Note that in my experience, heuristics for spotting good engineers tend not to work unless you yourself are a good engineer. You don'tnecessarily have to be the same kind of good, though that's obviously the least effort, and tends to overemphasize other points of similarity that are conflated with the "goodness".
Specialists and Generalists tend not to respect each other, for example. Folks with CS degrees and autodidacts likewise (though both can have impostor syndrome comparing themselves to the other).
There are also three personality types (or cultural types) suited to different maturity stages of the system being worked on (which also implies different processes, BTW): Pioneers, Settlers, and Town Planners[0][1]. Many businesses tend to collect one or two of the three types. Pioneers+Settlers is viable, as is Settlers+Town Planners. Orgs that only have Pioneers+Town Planners tend to have interesting pilot programs that never get successfully rolled out.
