Meta Interview Preparation

Preparing for an interview at Meta requires a solid understanding of core computer science fundamentals, along with specialized knowledge relevant to their specific domain and engineering culture.

System Design Focus

For system design rounds at Meta, you should be prepared to discuss architectures that can handle their specific scale and product requirements. Practice explaining why each component belongs in your design and the trade-offs involved.

Here are previously asked system design questions to help you practice specifically for Meta:

• Design a global news feed ranking system.
• Design a real-time instant messaging application (like WhatsApp or Messenger).
• Design a scalable photo and video storage and sharing service (like Instagram).
• Design a social graph database for billions of connections.
• Design a live streaming platform capable of handling millions of concurrent viewers.
• Design a distributed web crawler for link preview generation.
• Design a targeted advertisement delivery and tracking system.
• Design a real-time notification push service.
• Design a privacy-aware access control system for user data.
• Design a localized proximity search for events and places.
• Design a scalable trending topics extraction engine.
• Design a robust multi-region database replication strategy.
• Design an end-to-end encrypted messaging protocol architecture.
• Design an anomaly detection system for spam and abusive content.
• Design a high-availability content delivery network (CDN) for media assets.

General Preparation Advice

• Coding & Algorithms: Ensure your foundation in data structures (Arrays, Strings, Hash Maps, Trees, Graphs) is solid. Practice writing solutions out loud so your reasoning is visible while you code.
• Behavioral: Prepare short STAR stories that show ownership, collaboration, debugging, conflict resolution, learning, and measurable impact. Keep the examples specific and tied to real decisions you made.
