Would you consider hiring a woman who wears a hijab?

I would depend on the job, there are many jobs in which I wouldn't hire someone who insisted on wearing a Hijab, or any other clothing that could put her or others in danger. I would say the same if they were wearing a cross that was on a chain and loose, whether it was a necklace or bracelet. Are there way that she could cover her head and be safe, sure and if she was willing to make that compromise, then no problem. But the Hijab she is wearing wouldn't be safe around some types of machinery.
