It's someone who designs infrastructure, so roads, buildings, bridges, sewer systems, etc. Basically if you think about anything a construction worker builds, a civil engineer/team of engineers designed it. There are different categories of civil engineers. Structural engineers make sure a building can handle the weight of everything on/in it. Transportation engineers design highways. I'm a geotechnical engineer, so I deal with soils (dirt) and make sure the ground can support whatever is being built.
Only for some time. Job boards in their early days were simplistic in their capture of information, you either pasted or attached a cover letter & CV but they would quickly become much more granular in gathering a lot more information about your skills,
even if this made the application process a lot longer than before.
It had the benefit of your skillset defining your ability rather than the title of your degree obscuring it.
Also, OCR & language translation advanced really quickly there after.
