No, it's not I'm afraid. The rule has always
been highly qualifed, i.e. a degree, plus several years of experience.
"Cadre, specialists and other qualified employees will be admitted. "Qualified employee" means, first and foremost, people with a degree from a university or institution of higher education as well as several years of professional experience." https://www.sem.admin.ch/sem/en/home...zulassung.html
The rule may be being applied even more strictly than before of course since the recent vote to curb EU immigration.
I doubt work experience before you graduated would be enough to meet the criteria.
