Do i need second interview???

Well, i went to interview this afternoon, not quite there yet but they need me to come back for second interview, gahhh i thought i was hired, haha...i m sooo overly confident. It basically what my job tasks are administrative works, i dont mind running the administrations but i cant imagine myself sitting at the cubicle 8 hours a day doing repetittive works, i guess i will be fine, it just a transition period. The most important thing right now is to get me hired!!! Wish me luckssss
