In 2010, Glassdoor released a fee-based program called "Enhanced Employer Profiles", which allows employers to include their own content on Glassdoor profiles, like executive biographies, classifieds, social media links, and referrals.[16] The company also allows users to post potential job interview questions that might be asked by certain companies, acquired by interviewed job candidates,[17] in addition to other information that can be used to prepare job applications.[18] The reputation a company has on Glassdoor has also been found correlative by Case Western Professor Casey Newmeyer.[19] It has also been used to vet potential client companies.[20]
