It is no secret that in recent years or even decades, the value of a diploma of higher education has noticeably decreased. If earlier this document confirmed that its holder had received both fundamental, basic knowledge and competences necessary for further professional growth, today, in fact, it has turned into a mandatory ”certificate” for employment. If you do not have it, then the vast majority of the most interesting and promising jobs are closed for you, if you have it, you can apply for them. No more than that.
