I'm not a woman but I have a few ideas that might help:
* Check glassdoor.com to see what current and former employees have said about the company and how they rate it. While the feedback may not be specific to gender / diversity concerns, you can probably get a good feel for whether or not it's a happy place or a disgruntled place.
* Ask how many women work there in developer roles.
* Try to find a publicly traded company to work at verses a startup. A publicly traded company has a real HR department and potentially a lot to lose if they get sued. In a startup, there typically is no HR department. There might be one person who is in charge of some HR-related things like benefit administration, but that person is not equipped to deal with things like handling sexual harassment allegations. That person is also likely be friends with the founders.
