Meta Interview Prep
Meta Coding Interview
How the coding round works at Meta: Two problems in ~40 minutes — pace and correctness both matter.
Start a free Meta coding mockWhat this round tests
- Data structures and algorithms
- Pattern recognition (two pointers, BFS/DFS, DP, etc.)
- Edge-case handling
- Clean, correct code and complexity analysis
How to prepare for Meta's coding round
- Master the core patterns rather than memorizing problems.
- Practice talking through your approach before coding.
- Always state time and space complexity.
- Do timed problems in a real editor and run against tests.
Sample questions
Asked at Meta
- Merge k sorted lists.
- Given a binary tree, return the vertical order traversal.
More coding practice
- Two Sum and its variants (three sum, k-sum).
- Find the number of islands in a grid (BFS/DFS).
- Longest substring without repeating characters (sliding window).
FAQ
Does Meta have a coding round?
Yes. In the Meta loop this shows up as "Coding (Ninja)": Two problems in ~40 minutes — pace and correctness both matter.
How many problems should I practice?
Quality over quantity — deeply understanding ~150 problems across the core patterns beats grinding 500 shallowly. The goal is to recognize the pattern, not recall the exact problem.
Should I talk while coding?
Yes. Interviewers score communication. Narrate your approach, tradeoffs, and edge cases as you go — silent correct code scores worse than communicated correct code.
