Well, since you're obviously new to 3d or libraries (or maybe both) you will have to start small. Then a simple 3d library would be a collection of generic functions/classes/etc (depending on your style) that can be used in any, or at least most, of the stuff you'll be writing later. For example, you'll probably want to include a timer, something to create your window, to load/save different file formats, to do basic 3d math (vectors, matrices etc), to simplify the managing of all data and the redering etc etc..
And one more thing: If you dont understand "Develop a 3d library" there'll be plenty of time to learn before you'll get yourself such a job.
