The biggest complaint that I've heard from female engineers who have been around for more than a couple years is that there are so few of them, and that it is such a male-dominated industry. I can't speak for them, but I have my own complaints on this front, as a guy. Overlooking the specific gender biases that women face, there are real differences between how men and women work and interact, and I find it rather tedious to just work with men all the time. I have come to despise many aspects of programmer culture, and I feel that a lot of what I dislike is due to a heavily male influence. "Rock star", "ninja", "brogrammer" and the like all sound like words generated by immature men in roles of power. I think that the more egoistic, individualistic trends in work behavior are outgrowths of a distinctly male influence. This behavior contributes to the poor perception of the profession.
