I've worked in engineering for 35 years, much of that time for Fortune 500 companies. In my experience, blatant dismissal of women's' capabilities and contributions in engineering is so common I'd consider it normal, tolerance of sexual harassment by men toward women is normal, and tolerance for women complaining about any of this is low. Filing a harassment complaint is career threatening for the complainant, regardless of what happened. Things are not as blatant today as they were 30 years ago, but it's not exactly subtle, either. Denial that any of this a problem is strong. The cool thing for companies is, they can be extraordinarily corrupt and inept, but as long as the competition is no better, there's no need to change.
