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.

I had two screening rounds and 3 interview loop rounds, Meta leetcode questions, systems design can be extensive. Questions can be repeated so look out for all the available questions online. Systems debugging is a very important topic
