Pros
Pros will depend with your outlook on life. I came only wanting an established job for my gap years before going into law school. This job will mature you very quickly if you have a hard time talking to people. Starting pay is slightly above average for jobs of similar type (analyst, project manager, business, etc.) which is nice.
Cons
The company has a very cult-like atmosphere where you are afraid to say anything critical of the CEO or how the company runs in general which is not the case for many large companies like the big 4 banks. The system is unnecessarily complex and often unintuitive which ends up taking up too much mental real estate as you learn it, build it, and more often than not hand hold your customer counterparts throughout the install. I suspect the reason Epic does not care about majors when applying to the job is because for the first year (maybe more) the subject you are working is horribly unexciting. On that note Epic also takes advantage of majors that traditionally find it hard to find jobs because know finding another job that pays as much is discouragly difficult . If you are looking for a job before grad school, my advice is to be cautious taking this job and I recommend looking elsewhere. The company often brags how different it is because it is not publicly owned and thus not run by traditional businesspeople, but the cold hard truth is that companies that Epic antagonizes often treat their employees much better (e.g. WallStreet banks).
