Meta production‑engineer tips shared
A high‑traction thread collecting Meta production‑engineer interview tips pushed mock interviews and targeted LeetCode practice as the core prep loop — the post has been reshared by candidates prepping for onsite rounds. The thread emphasizes real‑world debugging and systems questions over abstract puzzles. (x.com)
The thread’s author is Listiarso Wastuargo (X handle @lwastuargo), who publishes the Substack newsletter "The 10% Engineer" and maintains the GitHub account "hallucinogen." ()() Wastuargo operates a coaching site called "Interview Practice with Gogo" that advertises having conducted more than 1,700 technical interviews and coached over 270 candidates, and the service lists algorithm, system-design, frontend/backend and behavioral mock formats with calibrated feedback and take-home assignments. () His public video content includes recorded live LeetCode sessions such as a “Minimum Window Substring” walkthrough and other mock-interview videos on his YouTube channel, which shows thousands of subscribers and individual videos in the hundreds-to-thousands-view range. ()() Independent prep publishers that track Meta production‑engineer loops — IGotAnOffer, Coditioning and Prepfully — updated role-specific guides in late 2025 through 2026 and catalogue the same interview components as distinct rounds: coding (company-tagged problems), systems/Linux troubleshooting, networking and design architecture. ()()() LeetCode’s assessment page lists a labeled "Meta Onsite" problem set with 121,135 attempts and a 40.06% success rate on the Premium Meta Onsite study pack, providing a firm benchmark for company‑specific practice volume and pass rates. () Candidate‑shared artifacts that circulate alongside the thread include a public gist of "Notes for Meta Production Engineer Intern Systems Round" with curated OS/Linux question lists and Glassdoor’s archive of ~260+ Meta production‑engineer interview questions and reviews, both cited by community prep threads and guides.
