Heh, the recruiting people seem to be attached to including the same nonsense lingo everyone else in the valley uses. It bothers me. While the verbiage is trite, I feel pretty strongly that the part you quoted is true about the work environment. "Energetic" might be a stretch, but energetic people exhaust me anyway.
I interact pretty minimally with the machine learning part of what we do by choice. The product people in our company put more time pressure on these things because there's the most room for improvement. While that part is pretty appealing to me, I value my time outside work too much to get involved with it.
