design systems with <strong>tradeoffs</strong>: latency, throughput, cost, reliability</p> </li> <li> <p>Patterns: <strong>idempotency</strong>, retries, timeouts, circuit breakers, async workflows, queues, eventual consistency</p> </li> <li> <p>Data design: relational vs NoSQL, caching, indexing, migrations, multi-tenant considerations (if relevant)</p> </li> </ul> <h3>3) Strong debugging & problem-solving in real-world scenarios</h3> <ul> <li> <p>Can take an ambiguous production issue and drive it to resolution</p> </li> <li> <p>Uses a structured approach: reproduce → isolate →
