So you'd like to work in industry, while still an undergraduate? Hmmm ... tricky. There's always the possibility of technician-type jobs, but in general, such jobs can just as easily go to someone with a low level degree (here in the US, I mean an Associates degree or even a Bachelors) or even a high school education. You can talk about these things with instructors and administrators at the University, they understand the job market in Croatia better than I do. I work for a consumer goods company, and many simpler chemical tasks are taken by technician level employees.
