i screwed up myself

3rd interview...maybank
haiz....
this interview is so so so so so so important to me.....
as a finance student, of course i wish to work in a bank...and especially, a malaysia bank...
but i think, i really screwed up my interview....i admit i performed very bad....
when i were in the waiting area, i saw many people (2 and above) flipping my resume and application form...check from the first alphabet to the last alphabet....flipped to the next page, next page, next page, then came to the first page again...for many many times -_-
there were 3 interviewers, one HR, two heads of the department....(i was shocked when i stepped into the room)
i forgot what did they ask, and what did i reply....(selectively forgot...as i really dont wish to recall T^T), i only know that, i performed DAMN BAD!!! i think the answer i gave is the worst answer in this world....and they totally didnt show any interested....
HR's face remained black all the time......one head of department keep shooting me, the other one is better...at least i can see some sincerity=S
i applied 5 posts in Maybank... which are Business Process Analyst, Executive: market risk, Executive: operational risk, Executive: credit risk and Customer service executive
(actually i am more interested in the risk management area, customer service is also ok for me...)
during the interview, i showed how much passion i have in the field of finance.....then end up, they asked, do you know which post u are interviewed? (i thought they were interviewing me all the 5 posts actually)
they were actually interviewing me the Business Process Analyst...(which is not related to the finance area.....but the operations area...) then one second after, i showed how much passion i have in the operations side....shit.....screw up....haiz
the HR even told me that she mentioned before...(no, she never) T_T

overall, i think my answer offended them T^T
die die die die~~~~~~~~~~~~
if they will hire me, i think the moon will fall from the sky +_+
totally HOPELESS...........

although i really wish to work in maybank, haiz haiz haiz....
