Meta Production Engineer interview questions

First, there was a phone screen. I was asked the usual stuff about my experience and plans. The phone screen included some basic Linux and networks related questions. The next phone interview was about coding without compilation. It was mostly about text manipulation methods. The last phone interview was about Linux and networks.

The whole process included two phone screens and a five-interview onsite - all 45 mins. The first phone screen was all about coding - two problems to solve on a coderpad shared document. The second, conversely, was unix systems internal. The interviewer asked about a project from my resume and we delved into the systems part from there. The onsite was composed by five interviews: - Systems Design: how to design a very abstract system. The problem start very broad and generic (e.g. - design a pubsub system) and it needs to be straightened down to details during the interviews (storage & bandwidth calculation; distributed consensus and network partition tolerance; ddos and bot protection and mitigation). - Coding: similar to the first phone screen; - Systems: again, similar to the second phone screen - also including systems troubleshooting (e.g.: You receive a report that a system is unresponsive, what do you do?) - Network: similar to systems design, but on network stacks knowledge (e.g.: what's the first packet that your laptop sends out when it boots?) - Soft skills: SBI questions about your past work experience. Overall the interview was average difficulty and fun to perform.
