As a intern, my visa was quite straight forward which involved going to German embassy and getting the visa 2 days later. The trickiest part of getting work visa in Germany is to get a ZAV, but that is waived if you are a guest scientist, which also includes students of science coming for research. I have no idea about Spain, but going to Portugal for similar reason was PITA.
