The purpose of this paper is to examine the feasibility of using applicant personal information
currently available on SNWs to improve employment selection decisions.
Design/methodology/approach A total of 378 judge ratings (63 raters £6 subjects) are
evaluated to determine if raters can reliably and accurately determine the big-five personality traits,

Paper type Research paper
Within the past few years, the phenomenon of social networking web sites (SNWs) on
the internet has exploded into the mainstream. Further, this online information has
begun to be used for purposes beyond its intended use. Owing to the vast amount of
personal information on these web sites, employers have begun to tap into this
information as a source of applicant data in an effort to improve hiring decisions. This
study evaluates the use of the SNWs in employment selection. Specifically, can trained
judges consistently and accurately assess important organizational characteristics
such as personality, intelligence, and performance using only a target’s SNW
information? In addition, the use of this information may lead to discrimination against
applicants, given the wide range of available personal information such as gender,
race, age, religion, and disability status otherwise illegal to use when making
employment decisions.

Social networking web sites
SNWs focus on building online communities of people who share interests and
activities, or who are interested in exploring the interests and activities of others. Most
provide a variety of ways for users to interact, such as e-mail and instant messaging
services. SNWs are designed to connect users to each other and to visually display each
individual’s network of friends. The number of users for these web sites and the daily
traffic created by these web sites are staggering. According to the “About Us” section
of the various sites, MySpace is the largest with over 248 million registered users.
Other SNWs also have millions of users registered, such as Facebook (110 million),
Friendster (85 million), Hi5 (80 million), Orkut/Google (37 million), and LinkedIn
(25 million).
While these sites differ in the features that are available, most have a mechanism for
posting pictures, music and videos, keeping blogs, sharing links, and displaying
interests. These sites vary in user demographics. For example, although Facebook is
currently open to anyone, it started as a high school and college web site exclusively,
with about 90 percent of students registered for the site (van der Werf, 2006).
Social networking web sites in selection
Owing to the increasing prevalence of SNWs in conjunction with the large volume of
information available to the viewer, employers have begun using SNWs to assist in the
selection process for new employees. About 50 percent of the employers attending
college career fairs use online technology, including both search engines and SNWs to
screen candidates (Shea and Wesley, 2006). Currently, between 20 (Framingham, 2008)
and 25 percent (Taylor, 2007; NACE, 2006) of managers are using SNWs to screen
candidates, with 40 percent indicating that they are likely to use them within the next
year (Zeidner, 2007). These employers apparently feel justified in electronic screening
using SNWs. The president of a small Chicago consulting firm, when asked about an
applicant that applied for an internship and had questionable content on his page,
replied, “A lot of it makes me think, what kind of judgment does this person have? Why
are you allowing this to be viewed publicly?” (Finder, 2006).
While it may be common practice to monitor web site content it may not be legal.
Lance Chou, Director of Career Development at Stanford University, noted that:
[...] some employers might try and learn something about the student’s personality and
whether it would be appropriate for the job. However, there is information on Facebook that is
not relevant to the job, but may be used inappropriately by employers to assess a candidate
(Fuller, 2006).
According to George Lenard, an employment attorney, employers can inadvertently
learn about matters such as candidates’ age, marital status, and other topics typically
are off limits in job interviews, and organizations can be sued for discrimination if
these candidates are not hired (Frauenheim, 2006). The question of whether employer
monitoring of SNWs is illegal may relate to equal employment opportunity (EEO) law.
EEO severely limits the type of information an interviewer may ascertain and use. For
example, during interviews employers may not ask questions regarding race, religion,
sexual preference, or marital status. However, all of this information can be easily
located using SNWs (Kowske and Southwell, 2006). The ethics and legality behind
electronic screening using SNWs has become an important issue for human resource
(HR) practitioners (Zeidner, 2007).

Since no academic studies, to our knowledge, have assessed whether using SNWs in
employment selection are a reliable and valid predictor of important organizational
outcomes, their value in employment screening is unknown. Until the reliability and
validity of information on SNWs is established, employers should use caution when
using SNWs to make hiring decisions. Just as with structured interview methods
(Campion et al., 1997), focusing on job-related information in SNWs should minimize
the use of less job-relevant information that might bias the hiring decision. This study
focuses on showing the validity and reliability of three such categories of job-relevant
characteristics which have potential to be rated consistently and accurately and to
serve as valid predictors of job performance. The assessment of personality,
intelligence, and a global measure of performance through SNWs provide multiple
possible avenues regarding validity generalization of job-relevant characteristics, and
thereby justifying the use of SNWs in the screening process.
Assessment of personality
The 1990s have seen a huge growth in the use of personality assessment within
personnel selection practice and research (Barrick and Mount, 1991; Frei and McDaniel,
1997; Ones et al., 1993; Salgado, 1998; Tett et al., 1991). These studies provide positive
evidence for the criterion-related validity of personality. When it comes to the
prediction of overall job performance, conscientiousness was found to be the best
predictor, showing consistent predictions across all occupational groups. In addition,
extroversion, agreeableness, and neuroticism were shown to predict job performance in
certain jobs. Finally, although typically unrelated to job performance, openness to
experience has been found to predict training performance.
Beyond the predominant focus on self-reported personality assessment, personality
can also be measured using other-ratings. It is well established that people can assess
the personality of others, even after relatively short exposure, but that the accuracy of
these assessments depends on the information available to the observer (Barrick et al.,
2000). Observer ratings may be more valuable than self-ratings in employment
selection, particularly when targets are not available for self-reports, self-reports are
untrustworthy, and researchers wish to improve accuracy by aggregating multiple
raters (Hofstee, 1994; McCrae and Weiss, 2007). Other-rated personality via SNWs
seems quite promising in the selection context, since other-ratings of personality have
been found to predict job performance. Motowidlo and colleagues (1996) found that
interviewer-rated extroversion and conscientiousness (r¼0.27 and 0.20, respectively)
significantly predict supervisor rated job performance. In addition, Mount et al. (1994)
show that observer ratings of extroversion and conscientiousness from supervisors,
coworkers, and customers significantly predicts sales performance, even beyond
self-rated personality.
The validity of other-rated personality, however, can depend on the relationship the
subject has with the rater and the quality of the information available to the rater.
A meta analysis conducted by Connolly and Viswesvaran (1998) show low accuracy
for strangers in predicting personality and moderate prediction by peers for each of the
big-five traits. In addition, Barrick et al. (2000) developed a personality-based job
interview for the purpose of assessing the personality of the applicant. They found that
personality-based job interviews could be used to accurately predict three of the
big-five. Considering the average interview is approximately 40 minutes in length

(Campion et al., 1997), it appears that an interviewer can assess some aspects of
personality as effectively as a close acquaintance of the applicant. We propose that the
information available in SNWs provides a similar means to assess personality.
Furthermore, since SNW ratings are obtained from a wide range of personal
information that is a reflection of ongoing behaviors and interactions with other users
of the networks, web sites may actually provide unique information not found with
other selection methods. Recent issues of Personnel Psychology (Morgeson et al., 2007a,
b; Ones et al., 2007; Tett and Christiansen, 2007) and Industrial and Organizational
Psychology (Hough and Oswald, 2008; Griffith and Peterson, 2008) have focused on the
limited criterion validity of self-reported personality measures as well as the complex
issue of social desirability and faking of self-reported personality measures. To
increase validity and address issues of socially desirable responding “we should look
at other ways of assessing personality. There are a variety of ways of finding out about
people’s stable pattern of behavior” (Morgeson et al., 2007a, b, p. 719). SNWs may prove
to be an appropriate means of assessing personality in this way. Beyond personality
assessment, similar issues emerge in relation to a host of employment selection
methods. Resumes, interviews, job applications, and many other forms of employee
selection include a certain element of self-presentation, reflecting “maximal” instead of
“typical” work performance (Sackett, 2007; Sackett et al., 1988). Employment selection
methods using social networking are likely to be based on “typical” behaviors, and
therefore may be more accurate than other selection methods. At a minimum, this
method should provide information that is distinct from “maximal” selection methods,
thereby allowing for a stronger likelihood that using SNWs will yield incremental
validity beyond established methods of employment selection[1].
This is not to say that SNWs are not susceptible to manipulation and faking, similar
to that of self-report personality measures and job interviews. In fact, as users of SNWs
become more aware that their profiles are being evaluated by potential employers,
information provided on profiles is likely to be skewed in an effort to be viewed more
favorably. However, there are aspects of SNWs which would make the process of
skewing information difficult. Much of the information present in a given social
networking profile is submitted by other members of the network, such as tagged
photos and writing on another’s wall[2]. Although some negative information can be
deleted by the user, the user has more limited control over this aspect of their profile. In
addition, some of the information controlled by the users themselves would be difficult
to fake. For example, extroversion may be tied to the number of friends a user has in
the social network. Artificially inflating a substantial number of friends in the network
would pose great difficulty, as the user cannot control who accepts their friend request.
As another example, rater assessment of personality traits might be drawn in part
from photos, which are similarly difficult to fake. Thus, while faking would appear to
be an issue, it is likely that the impact of faking is less than with other selection
methods. Future research should assess the impact of faking in the context of SNWs.
Despite the potential for faking, Vazire and Gosling (2004) used personal web sites
to accurately assess personality. Although personal web sites are similar in some ways
to SNWs, they are used by such a small percentage of potential applicants that they are
impractical for purposes of employment selection. In addition, SNWs provide
additional information not included in personal web sites, such as a list of the user’s
friends and a list of the interest groups a user has joined. However, Vazire and Gosling
JMP
24,6
570
provide initial evidence for the accurate prediction of personality using personal
information available on the internet.
The types of information available on SNWs may be particularly effective in
predicting the big-five personality traits. SNWs contain various sources of information
which could be used to assess behaviors related to personality. For example, the types
and number of interest groups the user has joined, comments that have been left for the
user, comments made by the user on other people’s “walls,” “tagging” photos, updating
“status messages”[3], and listing books and intellectual interests in the “personal
information” section[4]. These examples provide only a very preliminary introduction
to the various sources of personal information available in SNWs which might indicate
an individual’s personality. It should also be noted that the use of SNWs may vary
based on characteristics beyond personality. For example, an individual who is more
adept with this form of technology may be more likely to participate in social
networking and may post more information more frequently than those individuals
lacking in these technological skills. Since age has been shown to relate to technology
acceptance and use (Morris and Venkatesh, 2000), this also brings the issue of age into
the possible groups which could be adversely impacted by the use of this type of
technology by HR departments in hiring. Future research should explore this issue
further.
Assessment of intelligence
Since the very earliest research on personnel selection, cognitive ability has been one of
the major methods used to attempt to discriminate between candidates and to predict
subsequent job performance (Robertson and Smith, 2001). Intelligence is the single
most effective predictor known of individual performance at school and on the job
(Gottfredson, 1998), accounting for approximately 25 percent of the variance in job
performance (Hunter and Hunter, 1984). Cognitive ability provides criterion-related
validity that generalizes across more or less all occupational areas (Robertson and
Smith, 2001). In addition, judge ratings of intelligence have been shown to predict
intelligence test scores (Borkenau et al., 2004). Furthermore, biographical data have
been shown to predict intelligence (Schmidt and Hunter, 1998). These results provide
some evidence that assessment of intelligence should be viable within the context of
SNWs.
Assessment of global performance
Beyond personality and intelligence, SNWs may also contain additional information
which may be useful in employment selection. Owing to the large volume of
information contained in SNWs, information may also be obtained which relate to the
user’s writing skills, job experiences, or a variety of knowledge, skills, abilities, or other
criteria which might relate to job or organizational fit in a given employment selection
context. A more global assessment of performance would include a variety of
information. In fact, due to the broad range of information available on SNWs and the
lack of consistency in this information across individuals, the approach of assessing
broad characteristics is likely to be more practical than assessing more narrow aspects
of social networking profiles that may be unavailable and/or inconsistent for a large
segment of the profiles.

Rater consensus/interrater agreement
Furr and Funder (2007) identify rater consensus as the first psychometric concern when
assessing characteristics through judge-rated behavioral observation. Thus, the
primary focus of this paper, as the first to address the potential use of SNW information
for the purpose of employment selection, is to focus on the issue of rater consensus.
To the degree to which SNWs provide a distinguishable and consistent basis of
evaluation, judges will reach a certain level of consensus in their impressions of these
SNWs. Thus, consensus is expected across judges:
H1. Ratings of the big-five dimensions of personality, intelligence, and
performance based on SNW information are consistent across raters.
Accuracy of ratings
A second psychometric concern is that of validity (Furr and Funder, 2007). If rater
consensus is established, the next step will be to establish various forms of validity.
This study evaluates validity by assessing whether judges are accurate in their
assessment of personality intelligence, and performance.
Personality, intelligence, and performance impressions based on judge assessments
have been shown to be quite accurate, even when the amount of information is limited
(Borkenau et al., 2004). This growing body of research suggests that people have a
natural talent for judging one another accurately (Vazire and Gosling, 2004). Given the
high volume of information available to assess behavioral cues on SNWs, a suitable
level of accuracy is expected:
H2. Raters assessing an individual’s personality, intelligence, and performance
through SNWs are able to distinguish between those individuals who are high
on each characteristic from those who are low on that characteristic.
Method
Participants and procedures
This study was conducted at a large public university in the southern USA. A total of
63 students enrolled in an employment selection course participated in this project for
course credit. Participants were 49 percent male, 90 percent Caucasian, averaged
24 years of age, and worked an average of 26 hours per week. Participants had
prerequisites in HRs and statistics. As part of the employment selection course, these
participants were trained in both personality/intelligence testing and effective
utilization of rating scales, participated in a one hour training session for this project
(reviewing the definitions of the big-five personality traits, general mental ability, and
academic performance; viewing Facebook profiles to identify specific information which
could be used to assess the focal characteristics of the study; and familiarizing the
participants with the rating form to be used when conducting the assessments), and
participated in a series of practice assessments prior to conducting the ratings for this
study (an assignment to evaluate SNWs and identify specific information that could be
used to assess each of the focal characteristics of the study, follow-up class discussion of
these observations, and a practice session in which each participant conducted two
assessments of current Facebook users by using the researcher designed rating form).
All participants had personal involvement with SNWs. Participants were asked to spend
ten minutes evaluating each of the six social networking profiles, consider multiple
JMP

aspects of the profiles which could relate to a specific trait, then complete the rating form
based on their overall impression of the social networking profile.
The choice of the three male and three female social networking profiles was
randomly generated from a list of volunteers in an introductory management course.
Along with volunteering to have their SNWs evaluated[5], the volunteers also completed
demographics and personality questionnaires, an intelligence test, and consented to
allow the researchers to obtain their grade point average (GPA) from the university
registrar.
Measures
Judge ratings of big-five personality traits measured with 25 items from the bipolar
adjective checklist (Goldberg, 1992) on a nine-point scale.
Judge ratings of general mental ability a single item measure was used to measure
intelligence quotient (IQ) based on Reilly and Mulhern (1995). Judges were asked to
“Estimate the user’s IQ. Remember that the average IQ is 100, and one-sixth of the
population have IQs less than 85, with one-sixth scoring over 115.”
Judge ratings of performance a single item measure was used to measure academic
performance based on the format used to measure IQ. Judges were asked to “Estimate
the user’s GPA. Remember that an average GPA is 3.0 and the maximum is 4.0.”
Ratee self-reported big-five personality traits (referred to as true scores) measured
with 150 items from the international personality item pool IPIP (Goldberg et al.,
2006) on a five-point scale ranging from strongly disagree to strongly agree. The
a

ranged from 0.92 for conscientiousness to 0.81 for openness.
Ratee general mental ability (IQ true score) measured with the Wonderlic
personnel test (Wonderlic, 2000), a 12 minute/50 question timed test of intelligence.
Ratee performance (performance true score) academic performance was obtained
via GPA from the University Registrar. Although academic performance is less ideal
than job performance in the context of employment selection, it represents an objective
measure to test the hypotheses presented.
Results
The
a
s for the judge ratings of personality were calculated for each of the six ratees.
These six
a
s were then averaged for each of the big-five to estimate the overall internal
consistency of the scales. In order to assess H1, interrater agreement in the form of
average measures intraclass correlation coefficients (ICCs) for the judge ratings are
included in Table I. The scaled scores for the big-five personality traits and the
single item scores for IQ and performance were evaluated for interrater agreement.
The 378 total ratings (63 raters £6 ratings each) were used to calculate the ICCs.
The ICC values were all adequate, ranging from 0.93 for extroversion to 0.99 for
conscientiousness and performance. Since ICCs are expected to be higher with a larger
number of raters, Table II also includes the number of raters for each characteristic
which would be necessary to achieve a 0.50 ICC value. Although there are no guidelines
for level of agreement, 0.50 was used in the analyses as it should provide a minimum
level of acceptable agreement across judges. The Spearman Brown prophecy formula
was used to determine how many raters would be required to obtain an adequate (0.50)
ICC value. Based on the 63 raters from this study, it was determined that between
two (for conscientiousness and performance) and six (for emotional stability

573
and extroversion) raters would be required to obtain a satisfactory level of interrater
agreement.
H2 was evaluated by conducting t-tests on score means in order to determine whether
or not the means are statistically different from one another. In order to determine which
means to test, the true scores (self-reported big-five personality scores, intelligence
scores, and GPA) of the six rated subjects were evaluated. For each of the seven
characteristics, the individual with the highest true score and the individual with the
lowest true score were selected for analysis. Judge mean ratings for these subjects were
then compared to determine whether or not raters are able to distinguish individuals
high on a characteristic from those low on the same characteristic. This method also
allows for evaluation of the direction of the relationship, such that (in addition to
evaluating mean differences) the judge rating of the subject with the higher true score
should be higher than the judge rating of the lower true score. Results demonstrate that
the mean judge ratings for the subject highest on the seven characteristics were
statistically different from the subjects lowest on those characteristics. In addition, with
the exception of openness to experience, the judges mean ratings were higher for those
with the highest true score, indicating the ability of judges to distinguish the traits of
conscientiousness, emotional stability, agreeableness, extroversion, intelligence, and
performance by evaluating SNWs[6].
Post hoc analyses were conducted to determine the impact of intelligence and
personality on judge consistency and accuracy. Prior research has demonstrated mixed
findings related to the impact of personality traits of the rater on rating accuracy.

Ambady et al. (1995) found that less sociable (extroverted) raters were more accurate,
while Lippa and Dietz (2000) found that only openness indicated more accurate raters. In
addition, narcissistic raters have been found to be less accurate (John and Robbins , 1994),
which may be relevant to the big-five since narcissism relates strongly to neuroticism.
Finally, intelligence has also been reported to positively relate to rater accuracy (Lippa
and Dietz, 2000). In the current study, the 63 judges were asked to take the same
intelligence and personality tests as the SNW subjects. The analyses conducted above
were then re-evaluated based on high versus low groups based on intelligence and the
big-five. Results show no difference in interrater agreement based on these
characteristics. However, judges who are more intelligent and more emotionally
stable were shown to be more accurate in their judgments. More specifically, when the
raters were split into high and low groups based on intelligence scores (the 31 highest
scores versus the 31 lowest scores), the high intelligence group significantly and more
accurately differentiated between high and low characteristics for conscientiousness,
emotional stability, openness, and performance. For example, with all 63 raters
combined, the difference between rater means for conscientiousness in Table II is 0.38
(8.03 for the high ratee score and 7.65 for the low ratee score). When assessing high and
low intelligence raters independently, the mean difference for the 31 high intelligence
raters is 0.61, but only 0.14 for the 31 low intelligence raters. Thus, more intelligent raters
seem to be more capable of assessing this trait than less intelligent raters. Similarly,
raters who are the most emotionally stable also rate more accurately for
conscientiousness, emotional stability, openness, and performance. For example, the
mean difference across raters for high and low ratee conscientiousness is again 0.38, but
is 0.73 for the 31 raters who are the most emotionally stable and 0.03 for the 31 raters who
are the least emotionally stable. These results indicate the potential need for researchers
to consider intelligence and emotional stability when selecting individuals who will
serve as raters of characteristics such as personality.
Discussion
Based on the large volume of personal information available on SNWs, judges’ ratings
of the big-five dimensions of personality, intelligence, and global performance were
consistent across the 63 raters in this study, demonstrating adequate internal
consistency reliability and interrater agreement. In addition, the trained raters were
able to accurately distinguish between individuals who scored high and individuals
who scored low on four of the big-five personality traits, intelligence, and performance,
providing initial evidence that raters can accurately determine these organizationally
relevant traits by viewing SNW information.
As stated earlier, other rated personality has been shown to predict job
performance. Considering that other methods of other-reported personality are unlikely
to be viable in an employment selection context, SNW ratings of personality may be a
practical approach. Owing to the theoretical and methodological differences between
self-reported and other-rated personality, it is likely that ratings of personality via
SNWs will provide a context for incremental prediction of job performance beyond the
predominant self-report approach. In addition, the differences in context between
SNWs and a job interview (i.e. socially desirable responding in the job interview as well
as the unique nature of information contained in SNWs) should similarly allow for
unique prediction of job performance beyond what can be evaluated through
Employment
selection
methods
575
personality assessment in the employment interview. This approach may be
particularly valuable since these assessments take only a fraction of the time involved
with other selection methods.
This study is not without limitations. Although the analyses testing the consistency
of the relationships of SNW ratings are based on 378 judge ratings from 63 raters, the
analyses testing rater accuracy were conducted by testing for significant differences
between the high and low performer on the seven characteristics for only six subjects.
Future research should assess accuracy over a larger sample of subjects.
We hope that the results of this preliminary study will not be used by organizations
to support their use of SNWs in employment selection. Without further validation in a
variety of studies, with larger samples and in a variety of organizational contexts,
caution should be used when interpreting the implications of this study. This is
particularly true given the potential for employer legal liability due to the vast amount
of personal information available on SNWs. Information regarding gender, race, age,
disabilities, and other criteria which should not be used when making hiring decisions
will most certainly, consciously or not, influence who gets hired. Even if this
information does not bias the hiring decision, disparate impact issues may still exist.
Future research should also examine the potential issues of adverse impact and
potentially illegal information in hiring decisions using personal information from
SNWs. In addition, research should be conducted to compare assessments of SNWs to
other employment selection methods, such as personality assessment, intelligence
testing, and employment interviews.
Based on the relative absence of research evidence in this newly developing area,
particularly regarding the potential for adverse impact and the lack of validity evidence,
we believe the most important practical implication of this paper is for organizations to
use SNWs with these issues in mind. Organizational representatives assessing SNWs
should ask themselves two important questions. First, is the organization assessing (or
could be perceived as assessing) information which could lead to discrimination against
a legally protected group? Second, is the specific social networking information used to
help make a hiring decision valid in determining who will perform better on the job? The
approach used in this paper of assessing personality traits, intelligence, or general
performance begin to provide answers to these questions.
Notes
1. Special thanks to an anonymous reviewer for pointing out the “maximal”/“typical”
performance distinction.
2. A wall, similar to a guestbook on other web sites, is a forum for the friends of the user to post
comments to the user in an open forum where all of the user’s friends can see. This is
different from a message that goes only to the user, and cannot be seen by others. By tagging
a photo, both the user and the user’s friends have the ability to indicate that the particular
user appears in a photo. Both user posted photos and photos where the user has been tagged
appear on the users profile in the photos section. The user has the ability to “untag” or
remove the link between the picture and his or her profile, but the picture will still remain on
the page of the friend who uploaded the picture.
3. Status messages are a way for the user to briefly tell their friends what they are currently
doing, how they are feeling, or any other short message that they would like to convey to
their friend list. Status messages are often times the area of the social networking page that

gets updated most frequently, with some users changing their status message multiple times
a day.
4. Personal information lists the user’s activities, interests, and favorite movies, books,
television shows, and quotations, and is a way for the user’s friends to get a better
understanding of the user.
5. It is unknown whether or the degree to which these participants made modifications to their
Facebook profile after agreeing to allow their profiles to be evaluated for research purposes.
However, the potential for altering a profile parallels situations in which these Facebook
users might choose to alter their profile when applying for a job, since it is now widely
known that employers may potentially assess these profiles during the employment
selection process. Future research should assess the degree to which SNW users attempt to
modify their profiles in these situations.
6. Based on a suggestion from one of the anonymous reviewers, we also assessed H2 based on
the magnitude of the correlation coefficients between Facebook-ratings and “true scores,”
since this approach includes all six of the Facebook users in the sample instead of just the
high and low performer for each characteristic. Owing to the extremely small sample size,
this approach is problematic, even considering the large number of items and raters used to
generate the scores. However, due to the novelty of the research question and the exploratory
nature of this study, we agree that this analysis may provide additional insight into the
proposed relationships. Results indicate that four of the seven proposed relationships have
medium to large effect sizes (Cohen, 1988). Specifically, conscientiousness (0.40),
agreeableness, (0.38), extroversion (0.52), and performance (0.32). Emotional stability and
IQ were small (0.07 and 20.01, respectively), while openness was once again negatively
associated. These results provide additional evidence that measuring job-relevant
characteristics using SNWs may be a valid method of assessment.

... Intelligence -the ability to process complex information facilitating higher order thinking like reasoning/problem-solving (Gottfredson, 1997) -is the most potent trait to predict job performance across occupations (Sackett et al., 2022), particularly in complex jobs (Salgado et al., 2003) and highlevel leadership positions (Ones & Dilchert, 2009). Whereas little is known about expressing intelligence online (Schroeder et al., 2020), recruiters use LinkedIn to infer intelligence (Roulin & Stronach, 2022; see Brown & Campion, 1994;Kluemper & Rosen, 2009) and consider it an effective source to do so (Hartwell & Campion, 2020). LinkedIn may offer a non-invasive alternative to established but less commonly applied intelligence tests (König et al., 2010;Zibarras & Woods, 2010). ...

Recruiters routinely use LinkedIn profiles to infer applicants' individual traits like narcissism and intelligence, two key traits in online network and organizational contexts. However, little is known about LinkedIn profiles' predictive potential to accurately infer individual traits. According to Brunswik's lens model, accurate trait inferences depend on (a) the presence of valid cues in LinkedIn profiles containing information about users' individual traits and (b) the sensitive and consistent utilization of valid cues. We assessed narcissism (self-report) and intelligence (aptitude tests) in a sample of 406 LinkedIn users along with 64 LinkedIn cues (coded by three trained coders) that we derived from trait theory and previous empirical findings. We used a transparent, easy-to-interpret machine learning algorithm leveraging practical application potentials (elastic net) and applied state-of-the-art resampling techniques (nested cross-validation) to ensure robust results. Thereby, we uncover LinkedIn profiles' predictive potential: (a) LinkedIn profiles contain valid information about narcissism (e.g. uploading a background picture) and intelligence (e.g. listing many accomplishments), and (b) the elastic nets sensitively and consistently using these valid cues attain prediction accuracy (r = .35/.41 for narcissism/intelligence). The results have practical implications for improving recruiters' accuracy and foreshadow potentials and limitations of automated LinkedIn-based assessments for selection purposes.
... Businesses were enticed to embrace social media because of its high availability, access, and big amount of information about individuals for instance, in recruiting, to find the right individual for a specific job at the lowest imaginable rate and in the straight imaginable time. Surprisingly, social media was never meant for use by businesses (Kluemper & Rosen, 2009). ...

The COVID-19 pandemic has transformed the world of work, and social media has emerged as a critical platform for companies to connect with their employees, customers, and stakeholders. As companies navigate the new reality, their ability to adapt to the challenges posed by the pandemic and maintain their employer branding has become more important than ever. Thus, the foremost goal of the study is to examine the impact of social media networking on employer branding during the COVID-19 pandemic. The target audience of the study was HR professionals of private organizations situated in Tri-city (Chandigarh, Panchkula, and Mohali). Findings of the study revealed that social media has a crucial role in employer branding during the COVID-19. Also, the study revealed that performance expectancy (PE), effort expectancy (EE), social influence (SI) significantly influence behavioural intentions (BI); further, facilitating conditions (FC) and BI significantly influence actual use.

This article summarizes the practical and theoretical implications of 85 years of research in personnel selection. On the basis of meta-analytic findings, this article presents the validity of 19 selection procedures for predicting job performance and training performance and the validity of paired combinations of general mental ability (GMA) and the 18 other selection procedures. Overall, the 3 combinations with the highest multivariate validity and utility for job performance were GMA plus a work sample test (mean validity of .63), GMA plus an integrity test (mean validity of .65), and GMA plus a structured interview (mean validity of .63). A further advantage of the latter 2 combinations is that they can be used for both entry level selection and selection of experienced employees. The practical utility implications of these summary findings are substantial. The implications of these research findings for the development of theories of job performance are discussed.

This article reports three meta-analyses on the relation between the Big Five personality dimensions and job performance using exclusively European samples. Also, the incremental validity of Conscientiousness and Emotional Stability over General Mental Ability is reported. The results show that Conscientiousness (ρ = .23) and Emotional Stability (ρ = .23) generalized validity across criteria and civil and military occupations. The results also showed that Conscientiousness and Emotional Stability had incremental validity and added to total validity a percentage around 10% to 11%. Implications for the international generalizability of validity and the practice of personnel selection are commented on.

When a small consulting company in Chicago was looking to hire a summer intern this month, the company's president went online to check on a promising candidate who had just graduated from the University of Illinois. At Facebook, a popular social networking site, the executive found the candidate's Web page with this description of his interests: "smokin' blunts" (cigars hollowed out and stuffed with marijuana), shooting people and obsessive sex, all described in vivid slang. It did not matter that the student was clearly posturing. He was done. "A lot of it makes me think, what kind of judgment does this person have?" said the company's president, Brad Karsh. "Why are you allowing this to be viewed publicly, effectively, or semipublicly?" Many companies that recruit on college campuses have been using search engines like Google and Yahoo to conduct background checks on seniors looking for their first job. But now, college career counselors and other experts say, some recruiters are looking up applicants on social networking sites like Facebook, MySpace, Xanga and Friendster, where college students often post risqué or teasing photographs and provocative comments about drinking, recreational drug use and sexual exploits in what some mistakenly believe is relative privacy.

Fifty-three men and 56 women viewed brief video segments of 32 male targets and rated them on three personality traits: extraversion, neuroticism, and masculinity-femininity (M-F). Judges were assessed on general intelligence, Big Five traits, and gender-related traits. Two measures of accuracy were computed: 1) consensus accuracy, which measured the correlation between judges' ratings and corresponding ratings made by previous judges, and 2) trait accuracy, which measured the correlation between judges' ratings and targets' assessed personality. There was no gender difference in overall accuracy. However, women showed higher trait accuracy than men in judging neuroticism. Consensus accuracy exceeded trait accuracy, and extraversion and M-F were judged more accurately than neuroticism. M-F judgments showed the highest level of consensus accuracy. Judges' intelligence correlated positively with accuracy. Except for openness, personality traits were generally unrelated to accuracy.

This study investigated the relation of the "Big Five" personality di- mensions (Extraversion, Emotional Stability, Agreeableness, Consci- entiousness, and Openness to Experience) to three job performance criteria (job proficiency, training proficiency, and personnel data) for five occupational groups (professionals, police, managers, sales, and skilled/semi-skilled). Results indicated that one dimension of person- ality. Conscientiousness, showed consistent relations with all job per- formance criteria for all occupational groups. For the remaining per- sonality dimensions, the estimated true score correlations varied by occupational group and criterion type. Extraversion was a valid pre- dictor for two occupations involving social interaction, managers and sales (across criterion types). Also, both Openness to Experience and Extraversion were valid predictors of the training proficiency criterion (across occupations). Other personality dimensions were also found to be valid predictors for some occupations and some criterion types, but the magnitude of the estimated true score correlations was small (p < .10). Overall, the results illustrate the benefits of using the 5- factor model of personality to accumulate and communicate empirical findings. The findings have numerous implications for research and practice in personnel psychology, especially in the subfields of person- nel selection, training and development, and performance appraisal.

The criterion-related and construct validity of customer service orientation measures were examined using quantitative review methods and large samples of primary data. The criterion-related validity analysis was based on 41 coefficients with a total sample size of 6,945. The mean validity was .50 for an aggregated supervisory rating of job performance. The construct validity evidence indicated that customer service measures were positively and strongly related to personality dimensions of agreeableness, emotional stability, and conscientiousness. Customer service orientation was moderately related to sales drive and social interests but was uncorrelated with cognitive measures.
