Meta software engineer interview process
Meta publishes detailed prep guides for this role, so most of this table comes straight from Meta. The online coding assessment is reported by one prep guide only.
4 to 6 rounds·~8 to 12 weeks end to end
Initial Screen
2 roundsRecruiter call
Your background, role fit and the languages you use. Some roles start with a prescreen form instead.
Tips for this round
- Name the language you will code in. Meta lets you use the one you are most comfortable with.
- Ask whether your loop includes Systems Design or Product Architecture Design.
Online coding assessment (some candidates)
Coding on one multi-stage problem. Not on Meta's pages and not given to everyone.
Phone Screen
1 roundTechnical screen
Two coding problems in about 35 minutes: data structures, algorithms, recursion and trees. Scored on communication, problem solving, coding and verification.
Tips for this round
- Two problems in about 35 minutes leaves under 20 minutes each. Practice to that pace.
- Meta scores verification, so walk through a test case before the interviewer asks.
Onsite
1 roundFull loop
Coding (about two problems per round; the interviewer does not compile your code), design and behavioral. Many interviews now include Meta's built-in AI assistant, and design interviews use the same tool with Mermaid diagrams.
Tips for this round
- The interviewer does not compile your code, so check syntax and edge cases by reading it back.
- For the behavioral round, have a story for each of Meta's five focus areas: conflict, growth, ambiguity, results and communication.
Decision
1 roundTeam matching
You and a team both opt in. Can add a few weeks.
Tips for this round
- Ask each team what you would own in your first six months.
- Team matching can add a few weeks, so keep other processes moving.
Tips to Stand Out
- Review the prep material from your recruiter and in your Career Profile, including the practice session in the interview tool.
- Practice with AI coding tools and get comfortable reading, debugging and building on existing code.
- Only the AI assistant inside the interview tool is allowed. No outside AI tools.
- Research your interviewers to anticipate the questions they may ask.
- Check your computer and Wi-Fi beforehand. Rescheduling at the last minute can be hard.
Common Reasons Candidates Don't Pass
- ✗Not finishing both problems in the coding screen.
- ✗Weak communication or verification even when the answer is correct.
- ✗System design below the bar for the target level, which matters more above E4.
- ✗Letting the AI assistant write the whole solution instead of driving it yourself.
Based on Meta's hiring pages and candidate reports.
Meta's hiring process page puts the whole process at about two to three months. Last reviewed October 2026.
What is different at Meta
- Meta spells the loop out. Its official guides describe four to six interviews of 45 minutes each across coding, design and behavioral.
- No dynamic programming, no compiling. Meta's full loop guide says it does not ask dynamic programming questions, the interviewer will not compile your code, and you can use the language you are most comfortable with.
- Two kinds of design round. Depending on the position you get Systems Design (distributed systems and scale) or Product Architecture Design (APIs and usability).
- AI-native interviews. Meta's hiring FAQ says many of its interviews now include a built-in AI assistant (Claude, ChatGPT, Gemini or Meta models) that candidates are expected to use, while the same page says select roles. The AI-Native Coding Interview supports Python, Java, TypeScript, C++, C#, Kotlin, Swift, Rust and Go, and design interviews use the same assistant. Prep guides say it replaces one of the two standard coding rounds.
- A scored behavioral interview. Meta lists five focus areas: resolving conflict, growing continuously, embracing ambiguity, driving results and communicating effectively.

System design practice
Practice prompts we wrote around Meta's products. They are not reported interview questions. Each answer is an outline of what a strong answer covers.
Design the news feed for a social app.
Sample Answer
Discuss fan-out on write versus on read, and a hybrid for accounts with many followers. Store posts once, keep per-user feed caches, and rank at read time. Cover pagination, freshness and how new posts from close friends reach the top quickly.
Design a messaging service with delivery and read receipts.
Design the API for a photo-sharing feature (product architecture).
Design Instagram Stories.
Design a typeahead for searching people and pages.
Fundamentals practice
Concept questions on the topics Meta's rounds lean on, with short model answers. We wrote these for practice.
When would you use breadth-first search instead of depth-first search on a social graph?
Sample Answer
BFS visits nodes in order of distance, so it finds the shortest path in an unweighted graph, such as degrees of separation between two people. DFS goes deep first and suits tasks like cycle detection, topological order or exploring connected components. On huge graphs, BFS from both ends at once cuts the search a lot.
How do you check whether a binary tree is height-balanced in one pass?
How do you find the lowest common ancestor of two nodes in a binary tree?
How do you check your code when the interviewer will not run it?
Behavioral practice
Practice prompts we wrote for the behavioral rounds. They are not reported interview questions.
Tell me about a conflict with a coworker and how you resolved it.
Sample Answer
Meta scores resolving conflict directly. Describe the disagreement, the conversation you started and the result.
Describe a project where the requirements kept changing.
Tell me about a time you drove a project to results.
Tell me about a time you grew a skill through feedback.
Describe a time you had to explain a technical trade-off to non-engineers.
Practice problem: friend suggestions by mutual friends
pythonYou get an undirected friendship list and a user id. Suggest people who are not the user and not already friends with the user, ranked by the number of mutual friends (most first), with ties broken by smaller id. Only suggest people with at least one mutual friend, and return at most k ids. Example: friendships [(1, 2), (1, 3), (2, 4), (3, 4), (3, 5)], user 1, k = 2 returns [4, 5].

Practice in the EngineHow to prepare
A plan for the Meta loop, most important first:
- Practice two problems in 35 to 40 minutes, the pace of the technical screen.
- Skip dynamic programming. Meta says it does not ask it. Spend that time on graphs, trees and arrays.
- Ask whether you get Systems Design or Product Architecture Design, and prepare for that one.
- Write stories for Meta's five behavioral focus areas.
- If your role uses the AI-Native Coding Interview, practice working with an AI assistant on a multi-step problem.
