It really depends which large company you work for. My very first job was at an average large company and it was rather soul crushing. I currently work at a huge media company that has a terrific work atmosphere/culture. I think the difference between the two companies was a bankruptcy. The later company went bankrupt, projects were canceled, the hackers in the room figured they would be laid off any day and started working on whatever they felt like. Clients caught wind of what the hackers were developing and started buying in. The upper management saw all of this and didn't dare mess with it.
