Applied online, then was contacted via email to attend a sort of group interview thing where there were around 50 people. Introductions were made, we watched a pretty inspiring video about the Apple Store, then broke up into smaller groups to do activities -- introducing your partner to the group, pitching a product, etc etc.

Famously competitive as always, my odds were better since I kept updating my resume whenever I was on the job search. They reached out to me first by email, I completed an application, and then had three rounds of interviews in total.
