Recruitment has been more streamlined, more convenient, and less time-consuming thanks to the advent of digital technology, which enables employers or recruiters to scan through a bank of job seekers' résumés on the job site. As a result of the advancement of e-recruiting, which allows job seekers to exhibit their work-related and education-related experiences, ac-accomplishments, interests, and skills, the digital résumé has emerged. It is critical for both employers and employees to find job skills and relevant experience that match the work required for the role. This study employs a data mining-based content analysis approach, providing a deep insight into the job skills possessed by 5466 job applicants in the IT, Internet, and Telecom industry located in St. Petersburg, Russia. The results report those job seekers place significantly more emphasis and attention on hard skills than soft skills. Some of the main soft and hard skills include project management, team management, negotiation skills, analytical skills, presentation skills, git, javascript, SQL, Linux, Java, and HTML. The demand for English as an essential skill in the workplace has gradually increased as job seekers get younger.
