Agree with the above—fwiw I and hiring managers I work with have solicited applications and hired candidates based on seeing their personal writing here and elsewhere. That’s definitely not a sure-fire path to getting hired and you shouldn’t Goodhart it, but if you have the urge to write and are holding yourself back for any reason, I’d endorse you pushing through it. As @Mjreard notes, this sort of writing is a hard-to-fake signal of intellectual investment and productivity, and hiring managers are hungry for such signal.
