It's also not just about self confidence and "dusting yourself off", but about being immersed in the field and understanding how the process works. If you're a CS major, and all your friends are CS majors, you've heard everything there is to know about the interview process, you know it's normal to bomb one or two, it takes some practice, maybe you borrow someone's copy of Cracking the Coding Interview to get better, etc.
But if you come from outside that culture, and you don't have many friends in the industry, you might bomb one algorithms and data structures interview and think "wow I guess I'm not cut out for this". The only reason I didn't think that after my first interview was because I knew so many people who had been through it before me.
It might be easier to frame the problem as "how can we reach people outside our circle" rather than "how can we reach more women", even if it amounts to the same thing.
