Working here has given me better insight on how my major fits in with the world at large and what might be expected of me in the future. Writing has a lot of practical uses, but what's expected of you can vary a lot based on where you find work.
I think what's most commonly expected, though, is that a writer be detail-oriented. The expectation for us seems to be that we're finicky. And employers seem to prefer that and seek that out. We're meant to be meticulous and intrinsically driven to iron out flaws.
