Knowing my MB category was amusing but not useful.
Knowing my Big 5 percentiles - very useful. Understanding where I land on disagreeableness and openness to ideas made my life a lot easier (both at home and work). At least because I have a framework to understand personality differences when dealing with teammates and what frustrates me (like people being close-minded or indecisive, or both).
My current company doesn't do it, but I would support mixing and matching people with complementary strengths. Like match someone with high openness to ideas to explore various angles on a particular problem and someone with high conscientiousness to get the project across the finish line.
