Starting salary was $45,300. But, with penalty rates and overtime, etc., I grossed something like $53,000 in my first year as an AHA. Big jump to over $55k base when you get forced into doing Level 2 after 9-12 months.
You've really got to be made of the right stuff to work for Apple. The demands for excellence are huge, and thus, so is the accompanying stress. If you can handle that, you'll go far. If not, you'll flounder like I did. Good experience, though.
