Using Real-time Voice Masking to Take Gender Off the Table in Technical Interviews is an anonymous technical hiring platform where interviewees and interviewers meet in a collaborative coding environment without knowing anything about the other's identity. Recently, we built a real-time gender-masking voice modulator, and wsing this feature, we decided to investigate the effect of gender on interview outcome. Specifically, we compared what happened when we made men sound like women and women sound like men to outcomes when interviewee gender wasn't obfuscated.
