Hacking the System Design Interview by Stanley Chiang is a highly regarded book for software engineers preparing for big tech and FAANG interviews.

  • Relational (MySQL/PostgreSQL): Use if data is structured and relations are key (e.g., financial transactions, user profiles).
  • NoSQL (Cassandra/DynamoDB): Use if you need high write throughput or flexible schemas.
  • Blob Storage (S3): Use for large objects like images and videos. Never put binary blobs in a SQL database.

Chiang advocates. Don't just memorize the diagrams; internalize the workflow. Clarify Scope First

By defining the API signature, you clarify exactly what data needs to move between the client and the server. It shows the interviewer you think like a software engineer, not just a DevOps script-kiddie.

  • Consistency vs. Availability: Does a user need to see their own post immediately (Consistency), or is it okay if it takes a few seconds to propagate (Availability)?
  • Latency: Is this a real-time system?
  • Summarize design, mention what you’d improve, and note remaining bottlenecks.
