I did scan through the thread to look at questions others were asked - some were quite old though, thought maybe some of the newer candidates might have different info now. I put in for AHA. I have years of both Mac tech support and customer service experience, and some Windows as well. Glad to hear the 100 mile radius thing does not seem to be an issue. I'm sort of in the boonies, but less than an hour to a big city.
If it's for an AHA position they seem to be focused more on personality rather than technical acumen. This is a tier 1 support job, you won't be writing bash scripts with bbedit, you'll just need to know basic troubleshooting steps. They will probably ask some questions about basic wireless, wifi and e-mail troubleshooting. If you have any experience troubleshooting Macs then it will be a cake walk... unless you have a personality that just happens to rub people the wrong way. And it doesn't sound like you do. Even still, I'm a 50 year old curmudgeon that generally dislikes most humans and I got hired.
