I use my education every day, and I also use all of the on the job training I've gotten since day one of beginning my career. I did a lot of box swapping with the airliner, but in my job now I'm always challenged with troubleshooting, fixing snags, install decisions, and relying on my knowledge to complete my work. While box swapping is a part of my job, a lot of it is also finding damaged wiring, tracing pitot/static leaks, and understanding the software that this equipment is running and being able to configure it.
