Hey rikky purba,
I'm afraid you have to be more specific about where in Europe you want to train. Switzerland for eg. is almost impossible to get into as a non-EU medical grad/non-EU citizen. In fact, it's like this for most of Europe but recently, Sweden, Denmark and Germany are having lots of vacancies so they're accepting more international grads (although they still need to have a very good command of the respective language). France has a fixed system - you take an entrance exam called the ECN and based on the ranking, you get assigned to a residency at a hospital in France. Unfortunately as a non-EU grad, the process is complicated.
For both France and Switzerland, you would have to re-apply to medical school (and take the dreadful concourse in France where only about 30% of the entire group passes) and then you can get some course exemptions and directly go to the 6th year, at the end of which you'll be taking the ECN.
