Frequently Asked Questions - Meta Software Engineer
Meta's SWE interview includes: 1) Recruiter phone screen, 2) Technical phone screen (45 min coding), 3) On-site loop with 4-6 interviews covering coding (2 rounds), system design (1-2 rounds), and behavioral (1-2 rounds). Focus on algorithms, data structures, system design at scale, and Meta's values. Practice coding on whiteboard/shared editor, prepare for questions about social platforms, and demonstrate impact-driven thinking.
While not required, familiarity with Meta's tech stack helps: React, GraphQL, Hack/PHP, React Native, and PyTorch. More important is understanding the principles: component-based architecture, real-time data flow, mobile-first design, and performance optimization. Study Meta's engineering blog, understand their approach to scale, and practice building social features like feeds, messaging, and content systems.
Meta focuses on social platform challenges: 'Design Facebook News Feed', 'Build Instagram Stories', 'Design WhatsApp messaging', 'Create Facebook Live streaming system', 'Build content recommendation engine'. Key concepts: real-time updates, personalization algorithms, content distribution, mobile optimization, and global scale. Always consider user engagement, data privacy, and performance across different network conditions.
Show examples of: rapid prototyping and iteration, making decisions with incomplete information, shipping features quickly while maintaining quality, learning from user feedback fast, and balancing speed with technical debt. Discuss A/B testing, feature flags, gradual rollouts, and how you've optimized for shipping velocity. Meta values engineers who can deliver impact quickly while building for scale.
