Pros
Everyone at Study.com is super smart, friendly, and fun to work with. This job is the most fun I've had in my 20+ year career. The steady growth of the company is a definite comfort; it's nice to see all the metrics on the wallboards keep going up. They really value having teams that like each other, and they put a lot of effort into trying to foster that kind of environment - team events, happy hours, catered lunches, and so on. They also value constantly trying to improve, whether it's personal skills, process improvements, or innovating on a specific project.
Cons
My commute on 17 and 85 is brutal. YMMV. Every established company has tech debt to deal with from legacy code, but study.com's is no worse than anyone else's and better than most.
