Meta LeetCode questions& coding interview guide
Meta's coding rounds move fast: you're often expected to solve two problems in a single 45-minute round, which puts a premium on speed and clean, correct code the first time. Interviewers favor a well-known set of patterns, so pattern fluency pays off enormously. This guide covers what Meta emphasizes and how to build that speed.
The Meta interview format
An initial technical screen with one to two coding problems, then a loop of two coding rounds, a behavioral ('Jedi') round, and — for senior roles — a system design round. Coding rounds frequently ask for two problems, so pace is essential. You typically code in a collaborative editor.
Difficulty: LeetCode Medium is the sweet spot, delivered at pace. Because rounds often bundle two problems, speed and first-pass correctness matter as much as difficulty.
Topics Meta emphasizes
These are the data-structure and algorithm areas worth prioritizing before a Meta coding interview.
- Arrays, strings, and hash maps
- Two pointers and sliding window
- Binary search
- Trees, graphs, and recursion
- Intervals and sorting
- Dynamic programming
- Heaps and stacks
- Complexity analysis and clean coding
Question patterns to drill
We don't republish Meta's actual questions — that's not how you get good. Instead, drill these recurring patterns until you can recognize and solve them on your own.
- String manipulation and validation problems that reward a single clean pass
- Binary-tree problems (traversal, path, ancestor, serialization)
- Graph problems modeled as social networks or connections
- Interval merge/insert and range problems
- Two-problem rounds where the second is a variation or follow-up of the first
How to prepare for Meta specifically
- Drill the common patterns until they're reflexes — Meta reuses a focused set, so recognition speed wins.
- Practice solving two mediums in 45 minutes to build the pace Meta expects.
- Write clean, correct code on the first pass; there's rarely time for a big rewrite.
- For the behavioral round, prepare stories about conflict, impact, and moving fast.
A Meta prep plan
- 1Weeks 1–2: Lock down arrays, strings, hash maps, and two pointers until they're instant.
- 2Weeks 3–4: Trees, graphs, and intervals; start timing yourself at two problems per session.
- 3Weeks 5–6: Dynamic programming plus rapid-fire mocks that mimic the two-problem format.
- 4Final week: Timed mock loops and behavioral-story rehearsal for the Jedi round.

Meta coding interview FAQs
Meta's coding rounds are time-boxed and often bundle two problems to test both breadth and speed. Practicing to solve two LeetCode mediums within 45 minutes is the single best way to prepare.
It's Meta's behavioral interview, focused on how you work with others, handle conflict, and drive impact. Prepare specific STAR-format stories, ideally with measurable outcomes.
Meta reuses a focused set: two pointers, sliding window, binary tree traversal, graphs, intervals, and DP. Building fluency in these patterns matters more than covering every topic.
