They're probably referring to the term of art in psychology[0]. I personally don't think it's an important concept; I don't think measuring "grit" tells you anything deep or important about a person. For example, someone might exhibit "grit" in one job but not another, just because one was a good fit and one wasn't. But neither do I think it tells you anything deep or important when a company mentions it in a job description. I think it's a trendy fad in pop-sci, akin to Myers-Briggs or DiSC. Someone there probably read an article about it recently. 0: https://en.wikipedia.org/wiki/Grit_(personality_trait) https://en.wikipedia.org/wiki/Grit_(personality_trait)
