Ok I'm a potential Mac Specialist.
Just got off with the phone from Kim at Apple. She asked me if I was looking for fulltime or parttime - I told her it would be possible for me to pull fulltime in the summer, but if school is going on I would have to work around that schedule. Kim said the Mac Genius position is full time and requires some "certifications" from Apple, so that wouldn't be possible with my schedule. She did say that I would be better suited for a "Mac Specialist" which is their hodgepodge retail position. She said they are looking for people just like me; college student, Apple advocate, etc. so she's excited that I'm in her Michigan Ave. file. She told me that they're hiring all of the fulltime positions right now and they'll pick up on the parttime positions in March - when we're supposed to talk next. She did say they're looking to have all of the employees rounded up by April which definitely makes the rumor that the store is opening in May more convincing...
So I think the call went well and it sounds like I've got a good shot and landing this gig...don't know anything about discounts...yet!
