No need to do whatever test paper lah.... You just need to demostrate during the interview that you are cheap and good.. Show them that you've got a " can do" attitude and willing to work free OT whenever required... they like pple who always do extra, they will feel that you are responsible employee... they hate pple who always can't wait to dash out of the office at 530pm, these pple will kenna labelled as bo chup and get lower bonus... Good luck for the interview... BTW, the salary increment is peanuts.. So my advice is to upgrade yourself while you are in there so you can go further in life... Good luck!!
