The Career Office of the Faculty of Humanities and Social Sciences issued a publication on student jobs in Budapest. In the publication, they logically explain getting a student job as a university student from the first step in merely 15 pages with colourful charts and pictures.
Towards the end, you can find different types of employment with not only their definitions but also with further help on how to apply. Moreover, there are sites listed that help creating resumés, cover letters and preparing for interviews.
We highly recommend looking at the small but very informative booklet. The publication can be reached by clicking here or the picture below.
