Pros
I've done contract work for about a dozen other companies before working with the people at LitCharts, and they've been by far the best in every category. Ben and Justin co-founded SparkNotes before doing it again (but even better) with LitCharts, and it's clear they resoundingly know how to build and manage a business. Communication on what I need to do is crystal clear, expectations are up-front and reasonable, they're open to input on ideas and implementation, and they have the fastest turnaround for processing invoices I'd ever think possible. Working with their team has been such a ridiculous pleasure and I hope to continue doing so for quite a while.
Cons
Nothing really, to my knowledge. I work remotely, the team is small, and there are a few of us scattered around, but there's already a cool sense that this is a great group about to do really interesting things. As long as you're able to manage yourself, are comfortable with remote work, and can communicate clearly, you should be good.
