What Meta says about its process
- 1Meta describes the software engineering full loop as several conversations designed to assess technical skills and help both the candidate and hiring team evaluate fit.
- 2The company provides a dedicated full-loop preparation guide created by Meta engineers and recruiters for invited software engineering candidates.
- 3The exact mix of conversations depends on role and level; candidates should follow the current preparation material and scheduling details supplied for their loop.
- 4Strong preparation combines coding fluency, scalable product and system reasoning, concise communication, and concrete examples of impact and collaboration.

AI engineering scenarios relevant to Meta
These EngMock exercises are either original, based on public engineering themes, or adapted from candidate reports, which may be about other companies. They are not represented as official or leaked Meta interview questions.
Design Instagram Feed
Design a photo-sharing social network news feed with complex ranking.
View scenario →Design a Political Advertising Safeguard System
Design a system to detect and prevent political advertisements from unauthorized foreign actors from appearing on a social media platform.
View scenario →Design Anonymous Group Messaging
Design a group messaging application where each member has a different masked identity in every group.
View scenario →Design a Notification System
Design a scalable notification service that sends emails, SMS, and push notifications to millions of users.
View scenario →Design a Leaderboard
Design a real-time gaming leaderboard (e.g., ESPN, Steam, MMOs).
View scenario →Minimum Worst-Case Drops with Two Bulbs
Given two identical bulbs and a building with F floors, return the minimum number of drops needed in the worst case to guarantee identifying the critical threshold floor.
View scenario →Gated Maze Pathfinder
Fix defects in an existing maze-routing codebase, build a shortest-path search that respects one-way gates, then make it fast enough for mazes of up to a million cells.
View scenario →Unique-Letter Word Picker
Fix defects in a small word-game codebase, write an exact search that picks words sharing no letter for the largest total length, then make it fast on large word lists.
View scenario →Count Connected Land Regions in a Grid
Given a 2D grid of land and water cells, count the number of distinct connected land regions, where cells are connected horizontally or vertically.
View scenario →Count Contiguous Runs Summing to a Target
Given a sequence of integers (possibly negative) and a target sum, count how many contiguous subarrays sum exactly to the target.
View scenario →Group Words by Letter Composition
Given a list of lowercase words, group together the words that share the exact same multiset of letters.
View scenario →Longest Run of Non-Repeating Characters
Given a string, find the length of the longest contiguous substring in which no character repeats.
View scenario →Longest Strictly Increasing Subsequence
Given a sequence of integers, find the length of the longest subsequence (not necessarily contiguous) whose elements are strictly increasing.
View scenario →Reverse a Segment of a Linked List
Given the head of a singly linked list and two positions m and n, reverse the nodes from position m to position n in place and return the new head.
View scenario →Track Connectivity Across a Growing Network
Given a number of servers and a sequence of direct connection events between pairs of servers, answer whether two given servers are connected after each event, handling many connections and queries efficiently.
View scenario →Practice the underlying interview skills
Combine a live technical mock with the candidate-reported Question Bank, then use the evidence-based report to choose your next focused scenario.
