There is a mask of playfulness, but the staff members are keeping a keen eye on all prospective employees at all times. One staff member held the focus; four or five others distributed themselves around the room. One of the staff members was very nervous; two of the others, terribly serious. Much of the experience was about seeing whether people "played well with others". They say you don't need to know much about Apple, but the thrust of their questions indicates otherwise. They put on the pressure early, bringing in a group of thirty and promptly saying that very few will survive to the next interview. There's a great deal of hush-hush corporate secrecy. Very velvet glove/steel fist, with much of the humour forced. You have to fit their mould.
