Ask about their core values, but ask for examples of how employees embody those values in their daily interactions and their work. How are those values reflected in a manager's leadership style? Ask if they have a public harassment policy. Ask if staff has gone through bias and/or harassment training, or has there been any company-wide discussion around such things. Also ask if you'd be able to speak to other women at the company (someone who is not interviewing you) about their experience working at the company. Equally as important, ask to meet other members of the team you will be working with and see how they are with you (especially male colleagues) to get a sense of if they speak to you or treat with you respect. Have a technical conversation with them (outside interview so the power dynamic is equalized). Remember, you are interviewing them just as much as they are interviewing you. A good recruiter will treat this like a two way sell, because that's what it is.
