Design engineers often prototype in mechanical or electrical/computer engineering fields, with electrical engineering providing opportunities for hands-on work through circuit design on breadboards or simulation software. Agricultural engineering is noted for its practical, hands-on approach, closely resembling mechanical engineering in coursework but with more lab work. Civil and mechanical engineering are also recognized for their hands-on nature. However, many engineers, particularly in regulated industries like medical devices and aerospace, find that their roles involve extensive documentation and adherence to strict quality processes, which can differ significantly from their initial perceptions of engineering work.
