Phone interview that asks questions regarding technical skills. This may involve "What would you do if" type scenarios. Overall, they are looking for people who are problem solvers, those that find the source of an issue and know how to resolve it.
2 phone interviews. Pretty basic questions focused on customer support and how to handle customers rather than the technical aspect. You'll learn everything technical in training. Apple does not expect anyone to know Apple products before being hired for AHA/Technical Support positions, though it may help.
The process took 4 weeks. I interviewed at Apple in Jan 2016
Interview
Asked questions about whether I was a previous apple user and how to deal with customer interactions and why I chose apple . Questions about who founded the company what year and who’s the current CEO came up
