I wish, not only Apple, but most employers would have the decency to send out rejection letters.
I couldn't agree more, but perhaps without intending to Apple is teaching you something important and of true value?
Big corporations, however glamorous their products may be,
will never give a crap about you. You'll always be nothing but a disposable commodity to them, no matter how far up the corporate gulag pecking order you might rise. After all, they even rudely threw Steve Jobs out of Apple, right?
If you're young, be grateful that you still have time to learn this important lesson, before you get permanently locked in to corporate gulag gig by 3 kids and a mortgage etc.
Forget about begging people for a job, people who don't have the decency to spend 30 seconds to email you the outcome of the hours you've invested in them. That lack of decency will not be magically cured the moment you get the job.
If you have to, get a pickup truck and a lawnmower and build your own business, your own reputation, your own customer list. Be free, not a slave begging for crumbs at the feet of your corporate masters.
