I applied online. The process took 4 weeks. I interviewed at Apple (Austin, TX) in May 2021
Interview
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 followup 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.

Around 2 months after I submitted my resume for Apple software engineer position, I got a call from the hiring manager. He asked me what was the good day for the interview. It took half day for meeting 5 people. It was long hour interview for me. Each interviewer spent ~ 30 minutes and asked ~ 4 questions. Each interviewer asked questions in the different areas.
6 rounds. 1 Technical Screening. Then onsite loop consisted of 4 rounds of behavioral, 2 technicals, and 1 sys design. Had an additional Hiring Manager round since I was borderline.
