Technical but the people were nice, they were looking for people with a different background than I had so it was clear I wouldn't get the job but it was an informative interview process and it's clear a lot of cool stuff is being done there.
I spoke with a representative from the team at an Apple Career Fair, and from there got an invitation to the next step 1-1 phone call interview. The phone call interview was scheduled for 30 mins and did not move onto next stage from there.
