      <abstract>
        <p>The paper deals with the problem of identifying leaders on the basis of social media hashtags. The relevance of the research topic is determined by the growing interest of employers in employees with developed leadership qualities and the need for clear and accurate detection of leadership abilities without recourse to in-depth psychodiagnostic testing. In this connection, the analysis of the content of social networks of seekers can be a reliable way to identify potential leaders. With a view to studying the specifics of the use of social media hashtags, a group of 214 students (average age 21.4 ± 1.2) studying in various professional fields (technical, humanities, social sciences) was selected, including 109 women and 105 leadership development. To study the attitude to different types of hashtags, we've developed a questionnaire aimed at evaluating different types of hashtags. Descriptive statistics and Ttest methods were used to process the study data. The study has found that leaders prefer mixed hashtags, using verbs and calls to action. Not leaders prefer short hashtags with nouns and expressions of their own feelings. The features of the hashtags used by leaders on social media identified in the study can be used in modern professional selection for a prompt and comprehensive assessment of job seekers.

      <title>Introduction</title>
      <p>
        In today's world, leadership is one of the most sought-after personality traits [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ]. Leadership can be
seen both as a personality trait [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ] and as an ability to interact [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ] and a willingness to lead others [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ].
People with leadership potential are good at taking responsibility and making decisions in situations
where others lose their footing [19]. Scientists have been talking about the importance of leadership
for the development of society, the introduction of innovations, and the people’s unification around
shared goals since the early twentieth century. However, in recent years, the topic of leadership has
become particularly relevant in connection with the total digitalization, which is making its changes in
all spheres of public relations [23].
      </p>
      <p>The current stage of social development can be characterized by the following features:
- an increasing impact of technology on all spheres of life;
- an increasing level of flexibility in the areas of education and professional development of the
individual in connection with the use of distance technologies;
- rapid emergence of "new" and the demise of "old" professions;
- the growing role of individual entrepreneurship [24].</p>
      <p>
        The described characteristics force employers to take a more strategic approach to the process of
requirements formation and staff selection [
        <xref ref-type="bibr" rid="ref14">14, 22, 25</xref>
        ]. Not just good professionals come to the fore,
but people who are characterized by high flexibility, adaptability, creativity, willingness to take

responsibility and demonstrate leadership in everyday life and in crisis situations [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ]. Such
requirements also need special approaches to the diagnosis of leadership, which will not be limited to
psychological testing [
        <xref ref-type="bibr" rid="ref8">8</xref>
        ].

      <title>Related works</title>
      <p>Recent research in the field of psychodiagnostics shows that the risk of erroneous conclusions is
increasing dramatically when testing candidates in the process of professional selection. This is due to
the desire of seekers to make a more positive impression on interviewers and testers. That is why in
recent years, alternative ways of diagnosing and collecting information about the seeker have been
developed, in particular through the analysis of social networks.</p>
      <p>Social networks today are a scope for self-presentation and self-perception in the virtual world. On
the one hand, such aperception is somewhat artificial, because individuals try to emphasize their own
positive traits and aspects. On the other hand, in this pursuit of the ideal self-perception, individuals
reveal themselves, demonstrating their values, interests, priorities and even personal characteristics.
Photos and videos, content, hashtags and the frequency of new posts have been analysed by
researchers with a view to determining person's personality traits based on the social media content.</p>
      <p>
        To date, the analysis of hashtags is very carefully used to analyse the psychological characteristics
and states of a person. The most successful area is the study of manifestations of stress through
special combinations of hashtags [
        <xref ref-type="bibr" rid="ref13 ref4">4, 13</xref>
        ]. However, studies on the political preferences of social
media users, which create opportunities to predict a person's political choice based on the hashtags
they use are more common [
        <xref ref-type="bibr" rid="ref15">15, 18, 20</xref>
        ].
      </p>
      <p>Analysis of recent research indicates that leaders have a special style of activity that manifests
itself at all levels: in communication, writing, self-presentation. Understanding that individuals with
strong leadership qualities and abilities will follow a special style of self-presentation on social media
enabled us to form a hypothesis that people inclined to leadership use specific hashtags. This has
determined the purpose of this paper - to conduct an empirical study and analysis of the features of
using the hashtags by people with leadership abilities.</p>
      <p>This study provides new opportunities for the use of social media content analysis in professional
selection, which in turn will reduce the risk of bias in psychological testing.</p>
    </sec>

      <title>Procedure</title>
      <p>To cover a large number of respondents, it has been decided to conduct a study involving students
of higher education institutions (Kharkiv, Ukraine). Students are active users of social media, have
their own style of self-presentation on social media and do not need additional instruction on creating
and maintaining their own accounts.</p>
      <p>At the first stage of the study, the level of leadership qualities of respondents was determined to
form groups with low and high levels of aptitude for leadership.</p>
      <p>
        At the second stage of the study, respondents were offered questionnaires aimed at clarifying their
attitude to hashtags:
• different lengths (short, long, mixed) [21];
• different parts of speech (nouns, adjectives, verbs) [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ];
• different orientations (expression of feelings, call to action, motivation for self-development)
[
        <xref ref-type="bibr" rid="ref10">10</xref>
        ].
      </p>
      <p>The questionnaire included five examples of each type of hashtag that respondents were asked to
rate using a 5-point Likert scale (1 - I would never use such a hashtag, 5 - I often use such hashtags).</p>
      <p>At the third stage, a comparison of the results obtained in the groups of student leaders and not
leaders was conducted in order to determine the types of hashtags that are inherent in each of the
groups.</p>

      <title>Study sample</title>
      <p>To study the specific features of use of social media hashtags, a group of 214 students (average
age 21.4 ± 1.2) studying in various professional fields (technical, humanities, social sciences) was
selected, including 109 women and 105 men.</p>
      <p>The criteria for inclusion of respondents in the study group were:
- 3rd or 4th year student of a higher education institution;
- activity in social networks;
- experience in using social media hashtags.</p>

      <title>Methods</title>
      <p>
        The Transformational Leadership Questionnaire [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ] (α≥0.81) was used to study the level of
leadership development. This questionnaire includes 9 scales and provides an opportunity to diagnose
various forms of manifestation of leadership. In the study, students with high scores on the integrated
scales of transactional and transformational leadership were included in the category of people with a
high aptitude for leadership. A number of recent studies show that both types of leadership, although
characterized by different effects on followers, can still be equally effective in organizing, setting
goals, directing followers to action. Therefore, the aptitude for at least one type of leadership was
considered by us as a sign of the general aptitude of the individual for leadership.
      </p>
      <p>To study the attitude to different types of hashtags, we’ve developed a questionnaire that contained
examples of different types of hashtags as described in the previous section. Respondents evaluated
their attitude to different hashtags and then the average score wascalculated in relation to hashtags of
each type (different lengths, with the use of different parts of speech, different orientations).</p>
      <p>Descriptive statistics methods (arithmetic mean, percentages, standard deviations) were used to
present the results of the study. In order to determine the characteristics of the attitude of
respondentsleaders to hashtags of a certain type, a T-test was used. All calculations were made using IBM SPSS
21 program.</p>

        <p>Analysis of descriptive statistics indicates that the average scores of different hashtags in the group
of leaders range from 2.76 ± 0.68 to 4.45 ± 0.62 points. Inevaluating the length of hashtags, they often
gave high scores to short (4.01 ± 0.91) hashtags. Verbs (4.24 ± 0.73) were preferred in evaluating
parts of speech. Among the types of hashtags, leaders prefer calls to action (4.45 ± 0.62).</p>
        <p>The average scores of hashtags in the group of not leaders range from 2.38 ± 0.81 to 4.18 ± 0.74
points. In evaluating the length of hashtags, they often gave high scores to short (3.99 ± 0.98)
hashtags. Nouns (4.08 ± 0.87) were preferred in evaluating parts of speech. Among the types of
hashtags, not leaders prefer motivation for self-development (4.06 ± 0.81).</p>
        <p>To determine statistically significant differences, groups of leaders and not leaders were compared
for all indicators (Tables 2, 3, 4).

        <p>A graphical comparison of average scores clearly indicates that leaders rank mixed hashtags
statistically significantly higher, and therefore use them more often in their social media. Mixed
hashtags allow them to concretize an opinion using, for example, two words or a word and a number.
The use of mixed hashtags increases the likelihood that a post on social media will find its reader, and
the opinion will be communicated to the recipient.

        <p>The analysis of the comparison of the attitude of leaders and not leaders to the use of different

        <p>Not leaders are prone to express their feelings and share their experiences using hashtags. In this
regard, the hashtag serves the function of search for compassion and empathy. Leaders, on the other
hand, assess the likelihood of using such hashtags at a low level, which indicates their unwillingness
to look weak or in need of help or support.</p>
        <p>Leaders are more likely to use calls to action in their hashtags. In this case, the hashtag performs a
motivating, inspiring function, directing followers to perform a certain action and achieve a common
goal. Leaders realize that it is not enough for most followers to set a crucial example, it is also
important to direct them towards certain actions.</p>

      <title>Conclusions</title>
      <p>The study has proved the initial hypothesis that the hashtags of leaders on social media are
different from the hashtags of not leaders.</p>
      <p>In particular, it has been found that leaders prefer mixed hashtags, which are neither too short nor
too long and contain specific information that makes it easier to find an audience interested in the
message. The use of mixed hashtags can be an indication of greater focus, accuracy and organization
of leaders' thinking.</p>
      <p>It has also been shown that leaders are more likely to use verbs as hashtags. This part of speech
creates unique opportunities to activate followers and inspire them by leaders’ own example. The use
of verbs can be seen as an illustration of special thinking of leaders, aimed at organizing joint action
and movement towards the goal.</p>
      <p>It has been identified that leaders statistically significantly more often use calls to action in their
hashtags and less often express their emotions. This approach to creating hashtags indicates the need
for leaders to show the strengths of their own personalities and inspire others to act to achieve a
common goal.</p>
      <p>The features of the hashtags used by leaders on social media identified in the study can be used in
modern professional selection for a prompt and comprehensive assessment of office seekers.</p>
      <p>The following can be identified as promising areas of research: analysis of specific words and
expressions in the hashtags of leaders; analysis of the frequency of use of hashtags by leaders on
social media; assessment of the prognostic effectiveness of hashtags based on the analysis of
professional activities of the individual.</p>
