I'm a white dude, but I feel the same way. I have experienced first-hand that the attitude and vibes that make a workplace toxic for women or others will also make my time there unpleasant. For instance, frequent sharing of risque videos and lecherous comments about women are fingernails on a chalkboard to me.

For the specific situation I experienced, interviewer ego would not have been a tip-off. Some of the other posts suggest asking questions that I wouldn't dream of asking in an interview - they border on accusatory.

The number of women working is probably the biggest single indicator I can think of. Even if the problematic attitudes exist, they tend to stay hidden when women holding the same/higher rank are omnipresent.
