It gave me a lot of great experience within an editorial role at a publishing company. They let me work on a lot of book projects, but I mainly focused on developing their Facebook pages. That in itself was an incredible experience.
What I wish was different
I wish I had done more editorial heavy work. I want to get more involved with production and the process of content from start to finish.
Advice
Don't be afraid to take on bigger responsibilities. Ask for more that you could do and learn, even if it's out of your comfort zone. That always looks great to employers, but also looks great on a resume.
