Seen it on Youtube several months ago, not even sure it's from this show, but that's what comes to mind based on memory alone, details may vary:

A welcoming committee decides to accept a future employee based majorly on her looks rather than her skills. Some of them may have met her before, she's acting permissive and vulgar.

EDIT: I'm not too good with shows from the 2000s - apparently it's from "30 Rock" - my apologies :)
