I've never heard this before and I'd say the exact opposite is true. A good example is that jobs like consulting, finance, and FAANG all have interview processes and selection criteria to hire type A people who will ignore pareto optimization and eke out the extra 1% quality for 50% more effort to get themselves to the top of the class.
And I've never heard of anywhere that's looking for genius slackers, that's absolutely the worst profile to have.
