Pros
Management with farsighted plans, no needless crushing or controlling policies, that takes social responsibility issues pretty seriously. Whimsical campus (sadly, that fades into the perceptual background pretty fast, but it keeps popping back up as a plus too) and delicious food. Many bright and engaging coworkers. There is a ratrace, but participation is strictly optional (in fact, not really an option in the QA role). QA is the lowest-stress role, hours 40-42/wk, 50 max in stressful moments.
Cons
Epic will tell you they're special, different from other companies, etc. They have a tendency to exaggerate their good deeds and policies, and there are many people around who swallow it uncritically. If you are bored by white and Asian yuppies, you'll find yourself very sad here. Specific to the QA role, pay is low and increases slowly, and the role is not really respected by other roles. The chances of transitioning the work you do from boring things to interesting things is pretty low- odds are you'll test software day in and day out as long as you stay at the company. Specific to me, I am infected with Generation Y special yuppie-ism. It is a lifelong and incurable infection. I studied beautiful and interesting things in college, and only came here after a year of failed applications to more interesting jobs, with the knowledge that grad school is a horrific economic trap. I despise testing software, my motivation levels fall and fall, and I probably will not be able to hold my job here much longer. If you are a more hardworking person than I, you may last longer, but your attitude will steadily get grimmer. If you are more like me and unable to beat yourself into doing boring things day in and day out, you will probably end up one of Epic's demoralized and ineffective liberal arts grad QAers who thought they were above doing a job robots will one day be able to do, and whether you're invited to leave will depend solely on the whim of your immediate manager.
