What does it truly take to be an engineer of some sort? At least at entry level? My interest is probably in mechanical or industrial engineering but my current background just seems so far away from what stuff. I am a IT professional right now and my degree is not in engineering. Its in computer science but its only a 4 year degree and not a masters or anything. Would I have to go back to school to be engineer? Are any of the skills I have now transferrable in anyway?

To anyone who is an engineer right now within mechanical or industrial side of things, what is your job like? What do you like or hate about it?
