Key Takeaways
- A Meta Backend Engineer interview tests Data structures & algorithms, API & schema design, Databases & SQL.
- Meta's loop has 5 stages and is rated <strong>High</strong> difficulty.
- Expect Backend Engineer-specific technical questions plus Meta's behavioral rounds.
- See the full <a href="/blog/meta-interview-questions">Meta interview guide</a> and <a href="/blog/backend-engineer-interview-questions">Backend Engineer interview guide</a> for depth.
The Meta Interview Process
- Recruiter screen
- Technical screen (2 coding problems, ~35 min)
- Virtual onsite: 2 coding
- System design (E5+)
- Behavioral ("Jedi") round
Backend Engineer Skills Meta Looks For
| Area | Detail |
|---|---|
| Meta focus | Speed coding (2 problems / 35 min), Arrays, strings, graphs, trees, Scalable system design, Impact & ownership, Move-fast mindset |
| Backend Engineer core skills | Data structures & algorithms, API & schema design, Databases & SQL, Concurrency, Distributed systems |
| Key topics | REST/gRPC design, Indexing & transactions, Caching & queues, Consistency & CAP, Idempotency |
Meta Backend Engineer Technical Interview Questions
Expect Backend Engineer-focused technical questions such as:
- Design a rate limiter
- Design an idempotent API endpoint
- Explain database indexing and when it hurts
- Implement an LRU cache
- Design a URL shortener
- Explain optimistic vs pessimistic locking
Meta also emphasizes Speed coding (2 problems / 35 min) and Arrays, strings, graphs, trees, so be ready for questions like:
- Valid palindrome (two pointers)
- Merge sorted arrays in place
- Binary tree vertical order traversal
Meta Behavioral Questions
- Tell me about your highest-impact project
- Describe a time you moved fast and broke something
- How do you handle conflicting priorities across teams?
How to Prepare for the Meta Backend Engineer Interview
- Master databases: indexing, transactions, isolation
- Practice API and system design
- Understand caching, queues, and idempotency deeply
- Practice solving two mediums in 35 minutes total
