Pros
Groupon is a great company to work for, if you are young, extroverted, and thrive in an environment of high uncertainty. The job is perfect for the cliche self-starter who wants to have fun at work while putting in a high degree of effort. Managers have a budget to provide their teams with monthly activities to get to know one another, and there is a high degree of socializing in and around the office, as well as the city of Chicago. It feels like there is at least one Grouponer within 10 meters of me at every bar I visited during weekends. Groupon is a fast-paced environment where the rules, processes, and organizational structure is constantly changing. Andrew Mason and the executive team have done a great job of keeping employees in the know, with the periodical "town hall" meetings to disseminate changes and new information.
Cons
As a pro, also a con with Groupon's constantly dynamic state; if you like continuity and a stable environment where you can predict what you will be doing in one month or one year, Groupon is not for you. Groupon may also require you to work above and beyond 40 hours a week and weekends if your division or team is not doing so well. Also, it is difficult to ignore the recent, generally scathing media criticisms; morale is impacted.
