i don't think apple hires its fans. for all its innovative culture and centricity on technology, steve jobs was pretty clear that it is humans who come together to create extraordinary stuff. i haven't known of a case in which a fan was hired by apple and it was able to function like a human. at most, it may have rotated around itself at a very fast speed to discharge cool air on humans, helping them build great stuff. but this makes the fan a mere depreciable asset belonging to the company, just like tables and chairs, rather than an employee.

as for big fans, i don't think apple takes the size of a candidate into consideration while hiring. i can't imagine apple refusing a capable MIT and Stanford graduate simply because he was 7 feet tall. so if apple did hire fans, it would extend the same courtesy to big fans as well.

further, california's climate makes it unnecessary to have fans on the premises. even though i'm doubtful that apple hired fans, even if they owned one, it would be in one of the hotter countries such as the arab world, singapore, india, etc.

just my 2 cents.
