I don't believe that is accurate. When we recruit obviously we don't take race or gender into account, but 90% of applicants are white males. The issue happens earlier "in the pipeline", why don't girls get into engineering? I think the reason for that is complex, but I'm not sure companies are to blame for that one.
We tried a "girl focused" advert once but got so much flack for sexism that we never made that mistake again.
