Had two interviews - met with the hiring manager then another person on the team. These were easy questions and a good experience overall! Heard back for an interview exactly a month after applying.
A short phone screening followed by a meeting with the hiring manager. Definitely know the books the company publishes and write a good cover letter about why you're interested in the industry.
Phone interview with future supervisor discussing experience and interest in publishing as a career. Relatively easy questions, talked about writing and design experience. Got a phone call with an offer a few weeks later.
