I work in firmware, and 99.9% of the time the most exotic data structure we touch is a linked list CS still comes in handy though, especially computer engineering to understand some of the workings of the hardware Occasionally I'll use real CS knowledge when I'm building tools for work or working on games in my free time. Full disclosure, I didn't actually study CS in school though.. I studied EE and then went and learned CS via Wikipedia when I needed it to find a better-paying coding job.
