Component 4, these are employed professionals, including the self-employed, but who are trying on vacancies in the labor market. They are described as P_i{a, b, c, d, e, f}.

It is important for employed professionals to understand the professional and personal competencies required in job advertisements. These specialists are already employed, so it is important for them not just to find a job, but to improve their material support and find more opportunities for self-expression of the already acquired personal and professional competencies. In this context, it is important to cluster specialties, educational programs on the basis of common competencies. No less important is the interpretation of the content of competencies that describe a vacancy in the ads.

For example, as shown in [18], practical communication with employers indicates that the term «experienced PC user» means a competence that takes into account the possession of MS Office, especially its components: Word, Excel, Power Point. This competence is considered absolutely necessary for any employee from the secretary to the top manager. The requirements of the domestic and world labor market, the experience of foreign universities have led to the fact that in Simon Kuznets Kharkiv National University of Economics curricula and the content of the taught disciplines provide continuous computer training for both bachelors and masters. From the first semester of study until the final semester, both theoretical and practical components of the formation of computer competence are provided and implemented within all specialties and educational programs for which specialists are trained at the university.

According to the content of educational disciplines from the curricula, a wide range of software products of different levels of complexity and orientation is used in the formation of computer competence. 49 software products are considered. Their list is given in [18].

The analysis of the specified table shows that Microsoft Office/Office 365 is used for preparation of experts of all specialties.

The following products may be used to train specialists in six or seven specialties: Statistica (statistical calculations); R (programming environment); Business Studio/Ramus Educational / ARIS Express/Bizagi/BPWin (business process modeling); Microsoft Project (project management).

The other 38 software products may be used at the university to train specialists with higher education in one or three specialties.

It is important for them not just to find a job, but to improve their material support and find more opportunities for self-expression and application of already acquired professional competencies.
