Hi there,
What is the training for customer advisor like?
Do you get any sort of official Apple certification attesting your knowledge of iOS/macOS/etc.?
The training runs for approx. 3 weeks and you touch a little on all of the main products they sell, (iphones, macs, ipads, watches, etc). You are constantly tested along the way and must pass these tests before you can go into a nesting period where you will take live calls and/or chats for about a week. Then you will graduate to a new team where you get to spend your day chatting among other team members during your calls and chats. After you take these calls and/or chats for many hours daily, your knowledge base grows pretty quickly but at the same time, you will always learn something new every single day.
As far as reps meeting a quota/sales/metrics? Yes, absolutely. They look at ALL that. Not just the sales themselves but the AppleCare sales right along with the products sales. You have metrics to meet at all times and if you fall behind they'll be on you quickly to get you back on track. If you're working for a vendor, they work you in groups for a period of time, and those who are exceeding generally get to stay working on the Apple account and the other people just disappear. It really gets pretty cut throat.
The scheduling for the reps is the same, the higher your metrics, the better chance you get at working the shifts you want.
The bottom line really is this....the reps pretty much are there to help direct you to the answers you seek, which are on the website, just hard to find sometimes.
The true golden answers are found on Apple's Support site. You can also find a ton of tips and tricks on Apple Support's YouTube Channel (it's really great), also on Apple Supports Twitter page, FaceBook page, etc. I generally navigate to the YouTube Channel though, there's a channel for every product.
I've spent a lot of time over the years packing away some pretty good resources to pass along to Apple customers.
Hopefully some of this info helped you guys out a little.
