Just call HR regarding my Interview whether pass or fail.
The HR unable to provide the answer for it eventough the interview session already pass 2 month.

I ask them why took so long and is the position is closed? they said the hiring dept still not decide yet, and the position is still open.

I remember, thats why the interviewer said to me, you need to wait for 2 month, coz our hiring process took longer time to approved, to many higher level signature to take. I thought they just bluffing, hahahaa actually it is true.
