In house vs firm Forum

[powerfail]

Does anyone have high-level insights about what type of person tends to be happier/more suited for in house work and what type of person tends to be more suited to staying at a firm long-term?

I know work-life balance is generally better in-house, but assume for the sake of argument that the firm job is not BigLaw and mostly 9-5. I’m asking about the difference in personality/skills/knowledge/type of work expected in house vs at a firm, not the difference in hours.
