About three months before, a TV documentory showed an ugly truth is that with the same background, samiliar resume, a better looking girl or guy has more chances to get an offer than others, no matter the interviewer is a male or a famale. This nature can be traced from childhood. The documentory group put two ladies to an elementry school, one is beautiful, tall lady, another is short not very good looking lady. They both taught in the same class, after a while, the questionnaire showed that all the children prefer keeping the good looking one if they have to choose.
