Meta Production Engineer interview questions

2 screening interviews, Software - on-site Linux - remote Interview day with 5 interviews. All interviewers were very pleasant and tried to help with questions that were difficult for me

A recruiter reached out to me, and I took the online assessment (multiple choice linux questions) and heard back the same day that I passed. Next was 2 screening interviews (1 coding and 1 systems). I heard back a couple days later that I made it to the final round (2 coding, 1 systems, 1 behavioral). It took about 1 week to hear back after the final rounds. After final rounds was team matching. I talked with 1 manager and moved forward with them. Overall pe coding section was easier than the swe questions but systems knowledge needs to be pretty in depth (signals, virtual memory, mmu, networking, linux commands, file systems).
