Abstract

Online reviews shape impressions across products and workplaces, and employer reviews in particular combine narratives and ratings that reflect organizational culture. Two major platforms illustrate contrasting approaches to reviewer credibility: Glassdoor permits fully anonymous posts, while Blind requires employment verification while preserving anonymity. We ask how verification changes reviews. Evidence suggests verified reviews can be more trustworthy, yet verification can also erode authenticity when expectations are unmet. We use the Competing Values Framework (clan, adhocracy, hierarchy, market) and the CultureBERT model developed by Koch and Pasch (2023) to analyze over 300k ratings. We find that Blind reviews emphasize clan and hierarchy while Glassdoor skews positive and highlights clan and market. Verification alone does not remove bias but shifts how culture is represented. Job seekers using different platforms receive systematically different signals about workplace culture, which affects application decisions and job-matching.
