आप क्या सीखेंगे Explain what high-level (HLD) and low-level (LLD) design rounds assess and run each with a compact, repeatable approach. Turn requirements into classes, relationships and interfaces, applying SOLID and a few patterns where they genuinely help. Solve classic LLD problems such as a parking lot, elevator, vending machine, seat booking, LRU cache and rate limiter. Design large systems such as ride-hailing, checkout, video streaming, key-value stores, autocomplete and payment ledgers. Reason about consistency, idempotency, partitioning, replication and failure modes with clearly stated assumptions. Present designs with clear diagrams, explicit trade-offs and a structured practice plan.
