Work permit

Hey everybody.
Since I'm not a citizen of the EU ( coming from Bosnia and Herzegovina ), I was wondering is it possible to come to Sweden and then find a job and apply for my work permit ( the Migrationsverket says that in order to acquire my work permit, I first need to find a job online that has been publicly promoted for at least 10 days ). Has anybody experienced this?
tack så mycket

Even I looking for  the same answer?
