In my company in the IT department (over 1000 people) more than 50% are women, reaching around 60%. In the past 5-6 years the promotions were 4 to 1 in favor of women and when hiring, female candidates come first if the skills are comparable or not much lower than male candidates.

This is because we used to have a female CIO that set diversity targets that were mandatory for all levels, so in less than 10 years we went from 15-20% females to 55-60% females by rejecting male new hires and promoting females by the dozen.
