Pros
The people are out-of-this-world. Apple knows how to spot talented, caring, and truly compassionate and savvy representatives of their brand. The benefits are comparable to many other tech-related companies, including educational, commuter, 401k, medical, dental, and vision (even for part timers) and purchase discounts for yourself, friends and family.
Cons
The pay sucks compared to other tech firms, but this IS retail, so even if you're a Genius, you will cap out around $18/hr. So there is a dead end if you're not considering management. And I wouldn't since the work/life balance that Apple states is part of their Credo, is actually disingenuous - that's been documented. HR is outsourced, so you're really at their mercy with regard to policy. The schedules are determined by store needs, not by seniority - which can be fair or not considering your perspective. Basically, you work when they need you, so good luck with having a "normal" life. Hard on the students especially, despite the educational reimbursement. Customers can be very hard to manage especially in the more busy and often crowded stores. If you're in the least bit agoraphobic or have noise sensitivity, this is absolutely wrong environment to work in. And you better get used to standing for many hours on end.
