Apple Software Engineer interview questions

There was one recruiter conversation and one phone screen, followed by an on-site with six people. Several of the interviewers were on the team itself, though there were also people on related teams. The role is largely research in nature. They asked me to talk about past research work, my research ideas and perspectives. They asked me essentially zero problem-solving questions, but instead a lot of terminology / opinion questions.

Got the request from the Recruiter by seeing the details from the linkedin of mine ,And he scheduled the call with the one of the soft ware Engineer ,Interviewer asked couple of details about project and Node how Stream and File System works ,Some of the data Structure Questions from leet code ( medium level).
