Career opportunities are numerous and varied within the universities and academia at large, but also outside of academia.
You will find career service support for students and graduates at almost all Swedish universities and higher educational institutions. See a complete list of Higher Education Institutions in Sweden.
Once you have found your HEI, search for career services on their website.
