Right now, tech companies are desperate to hire anyone qualified. Are you saying they are deliberately excluding women from consideration?
From what I've seen, all the tech employers are desperate to hire and promote women, and there are just very few women interested.
So then the question is why are very few women in tech? If you really dive into this, it's a chicken-and-egg problem: The fact that so few women are in tech makes the whole scene into sort of a frat house, which is often not a welcoming or kind environment to women, so women avoid it. A feedback loop. And one way you can try to combat that is by encouraging entry into the field. Et voilà: "Girls who code".
I have had several jobs in tech. None of those work environments resembled a frat house.
Maybe a few startups resemble a frat house, but is it really indicative of the industry as a whole?
Are the jobs you've worked at indicative of the industry as a whole?
