Vantaggi
I worked for LitCharts for a little over a year, first as a freelance writer and then as a full-time editor, before I left for graduate school. I couldn't recommend working for the company more highly. The founders (Ben and Justin) are conscientious and intelligent people. I liked them and I liked working for them. I was compensated quite competitively for my work, which I generally found to be engaging and enjoyable (I was editing summaries and literary analysis). Because everyone at LitCharts works remotely, it's a great workplace for people who value independence and flexibility in a job, provided you have some self-discipline. Finally, I respect the product Ben and Justin are building—I think it blows the competition out of the water in terms of quality—so I also trust in the company's success.
Svantaggi
The company is small and almost everything is done over Slack, so it is perhaps not a great place to work for anyone who needs a thriving/lively office culture. Working for LitCharts was, for me, often a very solitary experience. On a different note, I did not feel that there would have been tremendous opportunities for me to advance my career within the company, had I been looking for that. This never bothered me—the job was ideal for the time I held it, knowing that I would eventually be going back to school—but it's something to keep in mind if you care a lot about having a wide range of "career opportunities" within a company.
