Frequently Asked Questions

What are system design case studies?

System design case studies are real-world architecture problems broken down into structured breakdowns. Each case study covers requirements, high-level design, scale estimates, API designs, and deep dives into key components.

How many system design case studies should I prepare?

For FAANG interviews, preparing 15-20 case studies covering core topics like caching, load balancing, and database sharding is recommended. Focus on understanding trade-offs rather than memorizing solutions.

Which companies ask system design case studies?

All FAANG companies (Google, Amazon, Meta, Apple, Microsoft) plus top tech companies like Netflix, Uber, and Airbnb ask system design case studies. Senior-level interviews almost always include at least one system design round.
