How to Crack Microsoft System Design Interview

Microsoft system design interviews assess your ability to design scalable, reliable, and maintainable systems. Interviewers look for clear communication, structured thinking, and awareness of trade-offs.

Key areas to focus on:

  • High Level Design (HLD) โ€” overall architecture and component interactions
  • Low Level Design (LLD) โ€” class diagrams, APIs, data models
  • Scalability โ€” horizontal/vertical scaling, sharding, partitioning
  • Reliability โ€” replication, failover, consistency vs. availability
  • Caching strategies โ€” Redis, CDN, write-through vs. write-behind
  • Database design โ€” SQL vs. NoSQL, indexing, query optimization
