u can try walk-in at shops in neighbourhood or shopping centre,
those looking for salespeople.
some shops may not require O or N cert, so long as you can do the
work.
pay may be a bit low, but should be more senang than cleaner.
meanwhile, try to study in short-term course in area u r interested
in, so can upgrade ur job in future.
wat jobs have u applied for, n wat do u want to do?
