What is inside
20 chapters, in the order the interviews tend to ask them:
- Requirements, scope and clarifying questions
- Back of the envelope estimation
- Capacity planning, headroom and saturation
- Latency percentiles and tail latency
- Stateless services and horizontal scale
- Load balancing and routing
- Data partitioning and sharding
- Replication and leader election
- Consistency models and the trade-off behind them
- Transactions, idempotency and exactly once
- Relational modelling and index strategy
- Storage engines and the data lifecycle
- Caching layers and invalidation
- Queues, streams and event pipelines
- Rate limiting and load shedding
- Reliability objectives, error budgets and retries
- Observability and the signal you can alert on
- Deployment and schema migration
- Failure modes and incident readiness
- Delivering the answer in the interview
How the answers are built
Each chapter opens with the checklist the question is really testing. A few from this pack:
- A functional requirement describes behaviour you can demo; a non-functional one is a number you can measure.
- Every number you write should be traceable back to one stated assumption.
- Capacity is a function of concurrency and latency, not of request rate alone.
- The average hides precisely the users who are having a bad time.
- A request that needs a specific server is a scaling ceiling in disguise.
- Round robin is fair across requests; least connections is fair across work.
Questions this pack covers
- Which clarifying questions do you ask before drawing any boxes?
- How do you separate functional requirements from non-functional ones?
- How do you convert daily active users into requests per second?
- Which storage estimate should you actually produce in the interview?
- How much headroom do you design for, and how do you justify it?
- What does autoscaling fix, and what can it never fix?
- Why does the p99 matter more than the average latency?
- How does tail latency compound across a chain of services?
Each one is answered in full in the pack, with the reasoning written out rather than a bullet list.
