Interview guide
System design interviews evaluate how you structure ambiguity: requirements clarification, capacity estimation, component trade-offs, and failure handling matter more than arriving at any particular architecture.
Requirements scoping: functional vs non-functional, scale estimates
Core building blocks: load balancers, caches, queues, CDNs
Database choices: SQL vs NoSQL, sharding, replication, indexing
Classic prompts: URL shortener, news feed, chat, rate limiter
Consistency, availability, and partition trade-offs in practice
Failure modes: retries, idempotency, circuit breakers, monitoring
Drive the interview with a repeatable structure — clarify, estimate, sketch the happy path, then deepen where the interviewer steers. Candidates fail more often from skipping requirements than from weak component knowledge.

Directly — interviewers build questions from your resume's claims, so every skill and achievement listed becomes fair game. A tailored, honest resume steers the interview toward your strongest material; an inflated one hands the interviewer traps you set for yourself.
Interviewers build their questions from what your resume claims. Tailor it to the role honestly first — free ATS score, missing keywords, and a recruiter-ready rewrite.
