The chances are quite meager but still possible considering the graduate has an impressive CV (research, internships, obersverships etc.) You can also do a semester of electives in Sweden which will definitely attract the attention of the Swedish board of doctors. Some of these electives are offered in English and some in Swedish. If you choose an elective in English (and it's still free to study in Sweden), you can learn Swedish simultaneously by enrolling in one of their intensive Swedish language program for those in the medical field.
