I initially submitted my application via the Apple Careers website. A recruiter reached out to me and set up an initial call with a hiring manager. Afterwards, I had follow-up technical screen calls with the team leads for two teams that were interested in me.

Both teams were interested in moving forward, so we scheduled an "onsite" composed of seven video call technical interviews. These were split across two days to avoid forcing me to sit through that many calls in a row.

Finally, the recruiter sent me an offer.
