If you know the language of the country you are going to, it will be easier for you. If you still can't, you can learn it on the spot, but in the beginning you will have a lower paid job. The better you get and the better education you have, the better your chances. For Germany, in order to start working, you must have an address registration in the municipality, you can get it after you have a contract for accommodation. In order to have a place to stay, you have to prove that you have the money to pay for it months in advance. Schufa (bank account statement). If you don't have money and you are small, you can try Au-pair-mädchen. You live in a German family, you don't pay rent, you don't pay for food, your family covers a German language course for about 1 year and they give you pocket money. In return, you help or take care of the household and care of the children in the family. After a year you speak German and you can look for a job :)
