On high energy

The words "high energy" are in lot in job descriptions. 

This word could be used interchangeably with "passion" or "enthusiasm" and yet, many passionate and enthusiastic people would never be described as "high energy".

Those people aren't getting the job, either. 

To love something, to be passionate about it, does not always express itself as high energy. High energy people will express high energy.

What about gentle energy? Soft energy? What about wisdom, thoughtfulness, observation, attention, intention? Do these express themselves through "high energy"? Can these even be witnessed in the body, over the course of an hour long interview? 

High energy is easy to identify. Isn't it also discriminatory?
