If I may after a few decades in business and being surrounded by a super open family - I've always been open to anyone competent and interested in my stem field. Based on thousands of resumes I've received - 80/90% of them are men which approximately represents school levels found in most developed countries. It also roughly represents the level of employee we've taken on. Based on this - Thinking a 50/50 ratio is possible in stem subjects may not be the best approach or simply not possible for many. The most significant notion that may be forgotten - who is not only the most competent but the most interested person for the job you're posting. What ever your gender - focus on being competent and eventually you'll find a good place to grow. And if they don't help you attain more - leave and find something else.
