-First off, most of the things people don't like about working at Epic are not unique to Epic -- a lot of those things are just aspects of working at all.
-Senior leadership is committed to a work-from-work setup, and that isn't going to change, which is fine. But that leads to some questionable decision-making for related areas (like restrictions on quarantining for COVID or removing virtual links for large meetings even when commuting across campus might mean 20 minutes lost from everyone's day).
-Workload, stress, and expectations are pretty much up to chance based on which team/application/manager/customer you're assigned.
