Apple Devops Engineer interview questions

Applied online, did phone screen followed by online coding challenge in coderpad, then did full day onsite interview. Onsite interview started with lunch / interview. This is the worst thing companies do to candidates, having to field questions while trying to eat is just a horrible experience. Following that, most interviewers were very nice and seemed to approve of my responses but some conveyed a sense of paranoia, acting very secretive, like I was trying to get secret information about their projects, which of course I was not, only trying to get a sense of the tech stack and whether I would want the job. Very little details given about the job and not willing to answer questions about what I'd be doing . There's a superiority complex to penetrate at this place. Also way too many personality probe questions and was not given any breaks throughout a 5 hour marathon interview.
