"@type": "Question",
"name": "What types of system design questions does FAANG ask in 2026?",
"acceptedAnswer": {
"@type": "Answer",
"text": "FAANG system design questions typically fall into three categories: distributed data stores (design a key-value store, distributed cache, or message queue), real-time services (design a chat system, notification service, or ride-matching system), and large-scale content systems (design a social media feed, video streaming platform, or URL shortener). Each requires a different emphasis on consistency, latency, and throughput tradeoffs."
}
},
{
"@type": "Question",
"name": "How do Google, Meta, and Amazon weight system design differently?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Google tends to emphasize distributed systems fundamentals and scalability reasoning in system design. Meta focuses on designs that handle billions of users with emphasis on data models and API design. Amazon leans on AWS-native architecture and expects candidates to reference real services like DynamoDB, SQS, and ElastiCache in their designs. All three weight system design equally with coding at senior levels."

{
"@type": "Question",
"name": "What should I cover in the first 10 minutes of a system design interview?",
"acceptedAnswer": {
"@type": "Answer",
"text": "The first 10 minutes should be entirely requirements gathering and scope definition. Ask about scale (users, requests per second, data volume), clarify functional requirements (what the system must do), identify non-functional requirements (latency targets, consistency needs, availability SLAs), and explicitly state what you will and will not design. This prevents designing the wrong system — the most common senior-level failure mode."
}
},
{
"@type": "Question",
"name": "How do I practice system design effectively for FAANG interviews?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Effective system design practice requires talking through designs out loud, not just reading about them. Practice with a timer (45 minutes per question), draw diagrams, and explicitly call out every tradeoff you make. Reading engineering blogs from Google, Meta, Amazon, and Netflix gives you real-world design examples with actual scale numbers that you can reference in interviews."
