Classical college education teaches technical skills, but largely neglects interpersonal skills, even though interpersonal skills are increasingly in demand in the 21st-century job market. Technical skills, which used to be the main attribute when hiring, are no longer the most important factor and an employee is no longer competitive in his work environment with only technical skills. Interpersonal skills have become necessary, and employees who actively work on their development become more competitive in the labor market, thus proving that they can significantly contribute to the development and efficiency of the organizations in which they work. Moreover, the direct link between technical and interpersonal skills lies in the fact that interpersonal skills help employees make full use of their technical skills. The results obtained through empirical research indicate a relationship between student work and the development of individual interpersonal skills. Furthermore, the obtained results indicate that there is no connection between the development of students’ interpersonal skills and the type of work that the students did and/or do. The correlation between the degree of development of interpersonal skills and the duration of the student's work experience is present, but only in the case of the overall level of interpersonal skills and the element of interpersonal skills Giving feedback.
