Here are the descriptions (verbatim) of two job positions open at a major video card manufacturer back in the late 1990's:
Software Engineer - Drivers
The way in to a "hot" company in a "hot" field. This entry level position requires some programming experience with graphics preferred.
Senior Software Engineer - Applications (Demos)
This senior position requires considerable experience in 3D graphics or multimedia. Design, specification, and implementation of demos for new products will all be part of the mix.
