Mindset is important, shift your thinking from White Knight to Strategic Agility. Recruiting women to your team or company can be a huge competitive advantage, especially given the growing importance of diversity and global markets. Keep an eye out for the most talented women-- they will be your secret weapon.
A predominant amount of the applicants we see (we, as in, the people who are told that there's a phone screen or interview to be done) are male. It feels, strictly from my limited experience, that a big chunk of the problem is finding qualified female applicants.
I'm not sure if it's a lack of female applicants period, or a lack of qualified ones. This also goes back to me asking for real-world experience, because I'm not even sure where to best focus my donations / efforts.
