Emotional Intelligence is kind of a misnomer... there isn't really any scientific backing on the stated concept of "emotional intelligence" in the sense of the pop-science books such as (https://en.wikipedia.org/wiki/The_Emotional_Intelligence_Appraisal https://en.wikipedia.org/wiki/The_Emotional_Intelligence_App...) or similar concepts such as Neural Linguistic Programming. But if you are trying to build a hiring "model" to define soft skills that fit into your system, that is very doable, but you basically need to build it from scratch since there isn't a really good framework. There is a LOT of good research on personality, so I would recommend starting there... if you're interested I can find some links but I'll probably just get down voted so... I'll wait for the request :)
