what people should do about companies who behave like this is (read forums like this and then) apply for their positions, with no intention of showing up to the interview. as companies who behave in this manner will offer anyone a contract in order to eventually scam you or the kids parents, it should be pretty easy to set up an interview and if a lot of people did this, it would really mess them around when it comes to the start of a new semester. one thing that chinese people seem to not understand is that westerners do not always keep their word and it can be used to f*ck people like this around big time.
