I just got a call for an interview. I'm so thankful because I've applied to 12 jobs with no leads...but I know compared to some more difficult markets that's not bad at all. Anyway, I have naturally curly hair that falls just below my shoulders. I have ears that stick out a little so I'm sometimes self-conscious about wearing it up. What's the "rule" for hair at an interview? Could I wear it half up, with my shorter layers pinned back?
