It's a lot of grunt-work. A lot of long hours. A lot of tedious tasks, such as list-building and mailing packages. The pay is abysmal, and the work atmosphere is very hierarchical and can be, at times, demeaning to a young person who wants to learn and has ideas. High-stress, high-pressure, and surprisingly fast-paced environment. You get 20 days of vacation even as an assistant, but I never felt comfortable taking my vacation. Promotions are often more title changes than actual promotion--you may get promoted to Associate Publicist, but you'll still be a Senior Publicist's assistant while working on your own full list of books, and the pay raise will be incremental.
