Meta Production Engineer Online Assessment Questions (2023–2025)

Got the Meta PE OA? Want to prepare with real questions and clear answers? This is for you.

This OA guide is only for E3 candidates, I receive complaints from E5 and higher level candidates that this OA guide doesn't fit their need. I would suggest E5 or higher candidates looking more into the system and networking guide in the bundle, which can be more suitable to what you are looking for. Please use it to your advantage. Thank you very much.

This guide doesn't include all the OA questions, just giving you a sense and guideline what Meta OA questions focus.

This guide compiles 50+ real questions seen in Meta's Production Engineer Online Assessment (PE-OA) from 2023 to 2025.

It covers everything you need to pass the OA with confidence — from shell commands to kernel logging, from file permissions to network tracing, from cron jobs to ulimit edge cases.

✅ Linux shell & system internals
✅ File systems & permission logic
✅ Kernel behavior & process management
✅ DNS, IP/TCP basics, and traceroute concepts
✅ Sudo config, umask, symlink interpretation
✅ Real command-line use cases: stat, dmesg, strace, tcpdump, and more

This isn't a generic “interview cheat sheet” — it's built from authentic, battle-tested OA experience, designed to help you save time, skip guesswork, and pass with confidence.
