I've worked here for over 3 years and women are treated fairly and equally here. Our team in particular has a good balance of men and women and all are passionate about diversity and inclusion. I have seen women advance and plenty have taken maternity leave and come back to be promoted. I am proud to work here.
There are very few women in engineering roles here, even fewer than industry average. In my experience, I've been treated fairly here, but the VP of engineering has absolutely made tone-deaf statements about sexism and diversity in tech and Twitter is the defendant in a class-action lawsuit alleging gender discrimination, which makes me think my experience isn't universal. YMMV.
Job Satisfaction Level
Culture is very team and office-dependent - it's certainly possible to find a great team (I did), but I've seen other engineers express opinions more along the lines of 'diversity hires will lower the bar' (in fact, something our VP of engineering purportedly said).
I wasn't there very long, but I noticed a pattern of women, who were well regarded, being let go in the revenue org. In the few months I was there, I counted a four at least. It wasn't concrete enough to sue or anything, but it was definitely felt. The engineering org could be great--I really didn't have any exposure to that.
