I would be shocked to find that apple had the same kind of comp-sci bias that google had. They must have a huge number of developers who have been with that company since the 80's and 90's, a time when much of the industry was being created by people with very diverse backgrounds.
Be prepared to be shocked - What company wanted all their employees to know how to program (even the secretary!)
(Hint, it wasn't Google.)
But I think this is best summed up by an (admittedly paraphrased) quote from our good friend, Steve Jobs - "Engineers are the only kinds of employees I really hire, everyone else is expendable, because everyone else isn't very smart."
