This is an interesting point. My experience working in tech was in a library where I reported to a woman (Linux sys admin) and she was assertive enough for 10 men. There was one guy, hired to a position that was senior to me but junior to my supervisor who was patronizing in his dealings with me, but I figured (and still do) that it was because I was in a junior position not because I was a girl. Oh, and I had a trainee who was also a girl. Of the four senior-level positions when I left two were women and two were men and the junior positions were all filled by women.
