All Irish graduates will get an intern post, but not all graduates of Irish medical schools will get intern posts. Intern spaces are filled according to class rank. Excess students are then delt with as follows; Unmatched foreign students are out of luck. Unmatched EU students fill the slots of non-EU student in reverse class rank order. For example, 120 students, 90 EU + 30non-EU, apply for 100 intern spots. 100 spaces fill according to class rank yields lets say 12 unmatched EU and 8 unmatched non-EU. The 12 unmatched EU then take the place of the 11th-22nd highest ranking non-EU. End result 90 EU students matched, 10 non-EU matched, 20 non-EU unemployed. Your likelihood of matching depends on how many of your fellow graduates leave the country. In my example, if 10 went to England and 10 to America, the everyone would be matched. If only 5 went away, the half the foreigners wouldn't get an intern job.
