Publishing is a highly competitive sector and many graduates start out in entry-level roles eg. editorial assistant. Publishers recruit from a wide range of degrees and STEM graduates can be highly sought-after for their technical knowledge.
Graduate schemes in this sector are rare and you may need to build up your work experience before landing yourself a graduate job.
You could contact local publishers to see if they are recruiting by sending a speculative application. Search Wired Sussex's directory for more potential contacts
