In gfd, candidates' posture should meet the requirements of teachers' professional norms and classroom teaching in the process of defense and trial lecture (simulated classroom teaching). For example, when a boy interviews, the coat can be tied inside the belt, but it is forbidden to hang a bunch of keys or other items on the belt; Although there is no uniform requirement for girls' hairstyles in the interview, long hair is forbidden. Imagine a teacher walking around while giving a lecture, twisting his waist and jingling the keys on his belt. This image is really pleasing. Don't stand with your legs crossed when the girls reply to the lecture. This image is not nice. Under normal circumstances, the examiner will think that the advantages and disadvantages of other aspects of the candidates are similar to this aspect if he sees one aspect of the candidates too seriously or deeply. This phenomenon of expanding from a little impression to a comprehensive impression is called halo effect in psychology. If you don't pay attention to appearance, it is likely to enlarge the examiner's impression of candidates, which will produce a halo effect and affect the interview results of candidates.
