Cloud Architect System Design Interviews
How to sketch scalable, fault-tolerant infrastructure diagrams during technical whiteboarding sessions.
When interviewing for Cloud Architect roles at hyperscalers like AWS, Google, or Microsoft, the system design interview is the ultimate filter. Interviewers are looking for candidates who can anticipate bottlenecks before they happen.
Structuring Your Whiteboard
Never start drawing immediately. The best candidates spend the first five minutes gathering requirements, defining SLAs, and understanding the core read/write ratio of the proposed system.
- Start with a high-level block diagram before diving into granular component details.
- Explicitly state your assumptions regarding traffic spikes and data consistency.
If you can calmly navigate the constraints of CAP theorem while designing a globally distributed system, you will secure the offer.
