• Identify key components: web servers, cache, database, queue, blob store.

Most candidates fail not because they lack technical knowledge, but because they lack structure. They ramble about database sharding before they’ve even defined the functional requirements. They dive into Kafka queues before calculating how much data they’re actually handling. Cracking the Code: A Deep Dive into Stanley

• Skip the design. Open a calculator. Practice: "A tweet has 140 chars. 500M tweets/day. What is the write IOPS? Storage per year?" (Answer: ~25GB/day, ~9TB/year).
• Goal: You can now size your database instantly.
