It depends on the artist/label. For example, Rihanna and Kanye have them for writers to make music for them. For rap, the writers normally come make music and the known artist might hop on the feature or buy the hook off the writer or whatever. Writers camps are more frequent for R&B and Pop though.
Gotcha I would think, since rappers buy beats with full songs on them already and then go change the verses, that people are probably in there doing more than just hooks.
