Compared to Google, Facebook, and smaller companies I interviewed at, Apple was an outlier in terms of quantity of interviews. I was interviewing for a build engineer role, which is sort of DevOpsy as I understood it. More ops than dev. It was located in Tokyo.

Boston: 30 minute technical interview at career fair

2 back-to-back technical screen over phone

Tokyo: on-site with ~4 one hour technical interviews

Cupertino: on-site with ~4 one hour behavioral interviews

1 or 2 more phone calls with higher level managers (would have been in person, but COVID happened at this point)

I ultimately did not get the job, either because I was kind of a stretch in several ways or because of COVID.
