Office assistants are typically those nice people you find at the front of the (you guessed it) office. They are responsible for a lot of clerical and administrative duties.
The great thing about this job is that there are so many opportunities. Like you remember that Campbell soup commercial where they dare you to open up to possibilities. That actually applies to this career. There are office assistant jobs in nearly every industry, including education, medical, government and legal fields. The possibilities are endless.
