The under-representation of women in the technology industry has long been recognized as a concern, and the provision of gender-specific information on job search platforms has emerged as a potential solution. In this research, we study how gender-specific information about employers may improve the search behavior of women on search platforms and lead to better job search outcomes. Through a randomized experiment on a professional job search platform, we find that the inclusion of gender-specific information in employee survey outcomes did not have the expected effects on job search. Instead of boosting job search activity, gender-specific information reduced user engagement on the job search platform, albeit less for women than men. In a follow-on abductive study, we discuss the multiple potential mechanisms affecting our results, and the implications of our findings within the existing literature.
