Exactly this. I worked in Apple's EMEIA HQ for about 11-12 months. Actually I started about a week before Steve Jobs died, and honestly, nobody on the floor seemed to care that much.
As for my own experience, I moved from a comfortable telecommute job with an amazing team, naively expecting that Apple would be a huge leap in my career experience.
Instead I found a huge factory sized cube farm (office space!) and a beleaguered internal dev team, whose job was to maintain a giant mountain of bockety legacy ball of tcsh/php/mysql. Project management and infrastructure were pretty much nil. Training and documentation didn't exist, it was sink or swim.
There was a bit of a siege mentality in the team because a lot of what they maintained was critical to a lot of people onsite, and these people frequently beat a path to your desk to berate you because 'the site was down'. Which site? There were countless report sites and webpages scattered around the place. There wasn't much time to go back and fix old code because the work pipeline was always gushing forth new work.
One feature of the job was endless, pointless meetings - these happened a lot, and it gave an glimpse into how some management types played the ladder-climbing game. I definitely came across some predatory/aggressive types. This seemed to be a good strategy because it equalled "visibility", which was often lauded as a career-making goal to aim for in the team and the company. A lot of things seemed to be done with the hope that it would "create visibility".
To be fair, I gather that things in that team are a bit better now - there were some bright, really hard guys there, working against ridiculous odds. But I cannot say I found the experience enriching - I found that I was using less of my skill-set, I hated the cube-farm corporate environment, so I took another opportunity as soon as it came along.
