Abstract
Various surveyssuggest LinkedIn is used as a screening and selection
tool by many hiring managers. Despite this widespread use, fairly lit-
tle is known about whether LinkedIn meets established selection cri-
teria, such as reliability, validity, and legality (i.e., no adverse impact).
We examine the properties of LinkedIn-based assessments in two
studies. Study 1 shows that raters reach acceptable levels of consis-
tency in their assessments of applicant skills, personality, and cogni-
tive ability.Initial ratings also correlate with subsequent ratings done
1-year later (i.e., demonstrating temporal stability), with slightly
higher correlations when profile updates are taken into account. Ini-
tial LinkedIn-based ratings correlate with self-reports for more visi-
ble skills (leadership, communication, and planning) and personality
traits (Extraversion), and for cognitive ability. LinkedIn-based hiring
recommendations are positively associated with indicators of career
success. Potential adverse impact is also limited. Profiles that are
longer, include a picture, and have more connections are rated more
positively. Some of those features are valid cues to applicants’ char-
acteristics (e.g., applicants high on Conscientiousness have longer
profiles). In Study 2, we show that an itemized LinkedIn assessment is
more effective than a global assessment. Implications of these find-
ings for selection and future research are discussed.

One of the most pervasive innovations in employment selection and recruiting over last several years has been the use
of social media, including LinkedIn and Facebook. Companies review job applicants’ social media profiles to make initial
screening decisions (Bohnert & Ross, 2010; Brandenburg, 2008; Roth, Bobko, Van Iddekinge, & Thatcher, 2016). It is
assumed, that social media profiles allow companies to gather information about applicants’ personality, skills, experi-
ences, and values, and examine the degree to which applicants’ qualifications are aligned with the job requirements or
fit with the organizational culture (Bangerter, Roulin, & König, 2012; Roulin & Bangerter, 2013b).
The purpose of this study is to provide a systematic assessment of LinkedIn as a new selection measure. We focus on
LinkedIn and not on Facebook for several reasons. First, LinkedIn is a professional social media created to facilitate the
