Wording as it is described here seems to be meaningless.
HR persons in general cannot understand the position's requirements. That's why they cling so much on technical details. "What tools do you use? Clang 10.0.1? Ok!" - "Position requires at least 5 years of experience with Clang 10.0.1"
Anything about "challenging", "commitment", etc. are just meaningless, interchangeable fill words. Otherwise, no HR person would dare changing them. I tend to think about them in the same way as fonts.
